Pd2(dba)3 (22.89 mg, 0.025 mmol), 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (43.4 mg, 0.075 mmol), 2,4-dichloropyridine (148 mg, 1.00 mmol), cesium carbonate (652 mg, 2.00 mmol) and 4-methyloxazol-2-amine (98 mg, 1.00 mmol) were added to an oven dried microwave vial, the vial was capped and placed under an inert atmosphere, dioxane (4 mL) was added and the resulting mixture was heated to 140 °C for 1 h by microwave irradiation under a nitrogen atmosphere. Dichloromethane (10 mL) was added to the crude reaction mixture and the mixture was adsorbed onto silica gel. The crude product was purified by flash silica chromatography, elution gradient 0 to 30% EtOAc in heptane. Pure fractions were evaporated to dryness to afford N-(4-chloropyridin-2-yl)-4-methyloxazol-2-amine (59.0 mg, 28.1 %) as a cream solid. Note: a further 34 mg of impure product came off the column early and so the yield for this reaction is probably closer to 35% had the purification been efficient. Conclusion: Somewhat surprisingly the methyl substituted amino-oxazole gave significant amounts of coupled product. It appears that certain moderately elctron rich substrates may also undergo relatively efficient coupling. |

The vessel was then heated to 120°C for 16 h. LCMS and TLC of the crude reaction mixture showed none of the desired product to be present. Some of the amine starting material appears to be present and none of the 2,4-dichloropyridine remains. The mass for the double addition product (addition at the 2- and 4-positions) is present, but co-elutes with the reaction solvent anisole and is not quantifiable as a result. Conclusion: This is a somewhat surprising result, based on the fact that the previous reaction (EN05378-17) results in the formation of significant coupled product. These reaction conditions are apparently not suitable for the coupling of the ester substituted 2-aminooxazole. |

To an oven-dried microwave vial was added ethyl 2-aminooxazole-5-carboxylate (546 mg, 3.50 mmol), 2,4-dichloropyridine (0.378 mL, 3.50 mmol), cesium carbonate (2279 mg, 6.99 mmol), TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0) (80 mg, 0.09 mmol) and (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (152 mg, 0.26 mmol) and the vial was capped and purged with nitrogen. dioxane (18 mL) (degassed) was added and the reaction mixture was heated to 160 °C for 1 h under microwave irradiation. LCMS of the crude reaction mixture shows the required product to be the major product together with an isomer of the same mass (Rt= 1.91), the ratio of the desired product to this isomeric product being circa 5:1. LCMS also shows that a small amount of the 2-aminooxazole ester starting material remains (Rt= 0.99 min) and so the reaction with this particular substrate may benefit from slightly longer reaction times, maybe 90 mins. A small amount of the coupled and decarboxylated product was also present (Rt= 1.68 min). Saturated ammonium chloride (15 mL) was added to the crude reaction mixture and the mixture was transfrred to a separating funnel. Ethyl acetate (80 mL) was then added and the organic layer was separated (keeping the interfacial material with the organic layer). The aqueous layer was washed with ethyl acetate (2 x 80 mL portions). (Note: During this extraction, a solid, presumably the required product was seen to crash out in the organic layer. If this reaction is to be repeated a work-up free approach is recommended where the crude reaction mixture is dry-loaded directly onto silica for chromatographic purification). The solvent was removed from the combined organics under reduced pressure. The crude product was loaded onto a pre- wetted silica column using the minimum DCM and methanol. The crude product was purified by flash silica chromatography, elution gradient 0 to 100% DCM (5% methanolic ammonia) in DCM. Pure fractions were evaporated to dryness to afford 744 mg of impure product. The crude residue was triturated with Et2O to give a solid which was collected by filtration and dried under vacuum to give ethyl 2-(4-chloropyridin-2-ylamino)oxazole-5-carboxylate (415 mg, 44.3 %) as a beige solid. Conclusion: The desired product was isolated in moderate yield and high purity (95% based on strength NMR). The moderate yield may be improved under a longer reaction time, it is also probable that purification difficulties were also detrimental to the yield of this reaction. |

Reaction (a): Control reaction under identical conditions to EN04881-40 (should produce similar yield) Reaction (b): As for control but spiked with 2 eq. of 2-aminooxazole with respect to catalyst, before dioxane was added (will produce decreased yield if 2-aminooxazole is a poison) Reaction (c): As for control but spiked with 1 eq. of N-(4-chloropyridin-2-yl)oxazol-2-amine, before dioxane was added (will produce decreased yield if N-(4-chloropyridin-2-yl)oxazol-2-amine is a poison) Pd2(dba)3 (22.89 mg, 0.025 mmol), 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (43.4 mg, 0.075 mmol), 2,4-dichloropyridine (148 mg, 1.00 mmol), cesium carbonate (651 mg, 2.00 mmol),ethyl 2-aminooxazole-5-carboxylate (156 mg, 1.00 mmol) and 4,4'-di-tert- butylbiphenyl (26.6 mg, 0.10 mmol) were added to an oven dried microwave vial, the vial was capped and placed under an inert atmosphere. Dioxane (4 mL) was added and the resulting mixture was heated to 140 °C for 1 h by microwave irradiation under a nitrogen atmosphere. An isolated yield was obtained for reaction (a). Dichloromethane (10 mL) was added to the crude reaction mixture and the mixture was adsorbed onto silica. The crude product was purified by flash silica chromatography, elution gradient 0 to 20% EtOAc in heptane. Pure fractions were evaporated to dryness to afford ethyl 2-(4-chloropyridin-2-ylamino)oxazole-5-carboxylate (111 mg, 41.5 %) as a white solid. Taking into account that the crude LCMS for reaction (A) corresponds to a ~ 42% isolated yield, the amount of product can be calculated for reactions (B) and (C) using the ratio between the t-Butyl biphenyl and the required product in the LCMS. The amount of required product produced in reaction (B) was 41% and for reaction (C) 45% product was produced. Conclusion: The above compounds do not poison the catalyst. Note: Significant amounts of what is assumed to be the regioisomeric 4-aminated product were also formed in these reactions. Major regioisomer formed in ~ 4:1 ratio. |

The vial was capped and placed under an inert atmosphere, dioxane (16 mL) was added and the resulting mixture was heated at 160 °C for 1 h by microwave irradiation under a nitrogen atmosphere. This reaction was run in four portions, i.e. four identical microwave reactions were carried out on 1/4 of the above scale. The reactions were then combined and purified as a single sample. Purification by chromatography on silica using heptane:ethyl acetate as eluent, on alumina with heptane:ethyl acetate and via reverse phase on C18 silica failed. The crude product was purified by flash silica chromatography, elution gradient 0 to 3% Methanolic ammonia (7 M) in DCM. Pure fractions were evaporated to dryness to afford ethyl 2-(4-chloropyridin-2-ylamino)oxazole-5-carboxylate (534 mg, 49.9 %) as a pale yellow solid. Althought the LCMS looks good for the fractions combined for this sample, the proton NMR shows significant impurities to be present.

To an oven-dried microwave vial was added ethyl 2-aminooxazole-5-carboxylate (156 mg, 1.00 mmol), 2,4-dichloropyridine (0.108 mL, 1.00 mmol), cesium carbonate (651 mg, 2.00 mmol), TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0) (22.87 mg, 0.02 mmol) and bis(3,5-bis(trifluoromethyl)phenyl)(2',4',6'-triisopropyl-3,6-dimethoxybiphenyl-2-yl)phosphine (80 mg, 0.10 mmol) and the vial was capped and purged with nitrogen. dioxane (4 mL) (degassed) was added and the reaction mixture was heated to 160 °C for 1 h under microwave irradiation. The reaction mixture was heated to 160°C for a further 3 h due to incomplete conversion. DCM (10 mL) was added to the crude reaction mixture together with silica (2 g). The solvent was then removed from the reaction mixture under reduced pressure. The resulting residue was then added tom a dry-load tube prior to chromatography. The crude product was purified by flash silica chromatography, elution gradient 0 to 2.5% methanolic ammonia (7 M) in DCM. The desired product (4-substitution) was isolated as a mixture with the 2-substituted product. The ratio of the 2-isomer to the 4-isomer is 2.4:1 for the mxture with no other fractions containing either isomer. Conclusion: The apparent higher selectivity for the 4-isomer is due to the overlap of the 2,4-dichloropyridine starting material with this isomer. Therefore this reaction actually forms the 2-isomer selectively and is not a very active catalyst for this transformation. |

An activated catalyst solution was prepared by adding TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0) (61.3 mg, 0.07 mmol) and (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (77 mg, 0.13 mmol) to an oven-dried microwave vial. The vial was then capped and purged with nitrogen and anisole (1 mL) (degassed) was added. The solution was stirred at 50°C for 40 mins, then 90°C for 15 mins (activated catalyst solution; Soln. 1). To another oven-dried microwave vial was added potassium carbonate (126 mg, 0.91 mmol), oxazol-2-amine (102 mg, 1.22 mmol) and 2,4-dichloropyridine (90 mg, 0.61 mmol) and the vial was capped and purged with nitrogen. anisole (1.35 mL) and the activated catalyst solution (0.45 mL of Soln. 1 from above) were then added (this corresponds to a catalyst loading of 10% Pd). The vessel was then heated to 120 °C for 16 h. LCMS of the crude reaction mixture indicated that the desired product was present (Rt= 1.70) along with a trace amount of the double addition product i.e. amine addition at the 2- and 4-position (Rt= 1.22 min). The reaction mixture was quenched with saturated ammonium chloride (8 mL) and transferred to a separating funnel. Ethyl acetate (15 mL) was then added and the organic layer was separated (keeping the interfacial material with the organic layer). The aqueous layer was washed with ethyl acetate (2 x 15 mL portions). The combined organics were then dried over sodium sulfate, filtered and the solvent was removed under reduced pressure. DCM (1 mL) was then added to the resulting residue (which still contained anisole (4 mL)) and this solution was loaded directly onto a silica column (40 g). The crude product was purified by flash silica chromatography, elution gradient 0 to 30% DCM (5% methanolic ammonia) in DCM, then 100% DCM (5% methanolic ammonia).

Note: the reaction mixture was degassed by first combing the reagents (with the exception of Pd((OAc)2), sealing the vessel and carrying out three pump- purge cycles (vac-nitrogen). Dioxane was then added to this mixture via syringe, followed by the Pd(OAc)2 in a single portion and the vessel was heated for the required time as above. Solvent boiled dry from reaction overnight. Only DMSO remained. **Crude proton NMR shows mainly dichlorpyridine starting material and the 2-aminooxazole starting material was absent**. Crude LCMS indicates that a product of the required mass is present. The crude product was purified by flash chromatography on C-18 modified silica, elution gradient 0 to 100% MeCN in water with basic modifier (1% ammonium hydroxide). Pure fractions were evaporated to dryness to afford N-(4-chloropyridin-2-yl)oxazol-2-amine (22.00 mg, 11.10 %) as a pale yellow residue. The product isolated, although impure, looks like the required product based on LCMS. The 1H NMR of the purified material is in D6-DMSO here and so not directly comparable with previous spectra in CDCl3. Conclusion: This may be worth pursuing (i.e. adding DMSO to aid solubility) based on the slightly increased yield. **Revision: Required product not isolated, spectral analysis of isolated sample does not match those of authentic samples of the coupled product** . |

The atmosphere was exchanged to nitrogen through consecutive vacuum- nitrogen purge cycles after which the mixture was heated at 120 °C for 16 h. Still some starting material left according to HPLC and LCMS (IPC 1), so another 25 mg of Pd(OAc)2 and 116 mg of BINAP was added, and heating continued. After another 4 h, no further progress was detected (IPC 2), so the mixture was allowed to cool to r.t. Dichloromethane (200 mL) was added and pH was adjusted to 2 by addition of 2M HCl (aq) (80 mL was added, but made too acidic). The phases were separated and the aq phase was made basic by addition of 1M NaOH (aq) (ca 70 mL). The aq phase was extracted with dichloromethane (200 mL) and re-extracted with another portion of dichloromethane (70 mL). Since the aq phase still contained some product, another portion of 1M NaOH (aq) (20 mL) was added and the aq phase was extracted with dichloromethane (100 mL). The combined organic layers were evaporated and toluene was added to co-evaporate water. The resulting brown solid was dried under vacuum o.n, yielding EN04391-37-001 (12 g, 27.1 mmol, 117 %). To the solid was added EtOAc (55 mL) and the slurry was stirred at r.t for 1 h. Stirring was turned off and the solid was allowed to sediment for 2 h. The solid was filtered off and washed with 2x 12 mL cold EtOAc, yielding EN04391-37-002 (5.7 g, 12.88 mmol, 55.7 %). The mother liquor still contained product so it was concentrated and to the residue was added isopropanol (18 mL, 2 mL/ g crude). The mixture was heated to dissolve everything (50 °C for 5 min) and was then stirred at r.t over night. A white precipitate had formed. The mixture was cooled on an ice bath (0-5 °C) for 1 h after which the solid was filtered off, washed with 2x10 mL cold isopropanol and dried at 40 °C under vacuum, yielding EN04391-37-003 (2.3 g, 5.20 mmol, 22.49 %). EN04391-37-002 and EN04391-37-003 were combined with EN04391-36-002 and EN04391-36-003 and further purified, see page EN04391-38. |

The atmosphere was exchanged to nitrogen through consecutive vacuum- nitrogen purge cycles after which the mixture was heated at 120 °C for 18 h. Still some starting material left according to HPLC and LCMS (IPC 1), so another 25 mg of Pd(OAc)2 and 116 mg of BINAP was added, and heating continued. After another 3 h, approx. 2% starting material remained according to LCMS (IPC 2), so the mixture was allowed to cool to r.t. Dichloromethane (200 mL) was added and pH was adjusted to 2 by addition of 2M HCl (aq) (140 mL was added, but made too acidic). The phases were separated and the aq phase was made basic by addition of 1M NaOH (aq) (ca 200 mL). The aq phase was extracted with dichloromethane (200 mL) and re-extracted with another portion of dichloromethane (70 mL). Since an oily residue containing product had precipitated upon addition of acid/ base, the aq phase together with 100 mL dichloromethane was added to the residue in an attempt to dissolve it. More 1M NaOH (aq) was added to assure basic pH and the layers were separated. The combined organic layers were evaporated and the residue was dried under vacuum o.n. EN04391-36-001 (12.2 g, 27.6 mmol, 109 %) was obtained as a brown solid. To the solid was added isopropanol (48 mL, 4 mL/g crude prod) and the thick suspension was heated at 95 °C. After 30 min, the slurry was allowed to cool to r.t and left stirring over night. The still thick slurry was cooled on an ice bath at 0-5 °C for 1 h before it was filtered. The solid was washed with 4x15 mL of cold isopropanol and dried at 40 °C under vacuum o.n, yielding EN04391-36-002 (2.05 g, 4.63 mmol, 18.38 %) as a pale yellow solid The mother liquor that still contained product was concentrated. An orange- brown foam was obtained. Toluene was added and evaporated and the residue (8 g) was dissolved in MeCN (13.5 mL) and purified by chromatography (200 g SiO2 in a filter funnel, elutent: EtOAc (750 mL) followed by MeCN (1 L) and MeCN:MeOH 9:1 (1 L)). Fractions 10-13 were combined, concentrated and dried, yielding EN04391-36-003 (5.5 g, 12.43 mmol, 49.3 %) as a solid. EN04391-36-002 and EN04391-36-003 were further purified on page EN04391-38. |
