The reaction was stirred at 0° C. for 5 minutes, then warmed to 65° C. for 3 hours. The reaction mixture was cooled to 0° C. and 6N HCl (6 ml) was added carefully. The solvent was removed in vacuo, and the residue was repeatedly concentrated from methanol (3×10 mL). The product was dissolved in 12N HCl and heated at reflux for 20 hours. After cooling, the volatile materials were removed under vacuum, the residue was dissolved in water (10 mL) and then concentrated to give 1.05 g of Compound No. 158 as a hygroscopic glass. |
Here is a chemical reaction formula: Reactants are:m1_m4_m2_m3_m5:C(C1=CC=CC=C1)(=O)Cl;m1_m4_m2_m3_m5:NCCCCC(P(OCC)(=O)OCC)P(OCC)(=O)OCC;m1_m4_m2_m3_m5:C(C)N(CC)CC, Reagents are:m1_m4_m2_m3_m5:ClCCl;m1_m4_m2_m3_m5:ClCCl, and Products are 0:C(C1=CC=CC=C1)(=O)NCCCCC(P(OCC)(=O)OCC)P(OCC)(=O)OCC, please give me the reaction condition of this formula. | The condition of this chemical reaction is: A solution of benzoyl chloride (0.73 g, 5.0 mmol) in dichloromethane was added slowly to a solution of tetraethyl 5-aminopentane-1,1-bisphosphonate (1.50 g, 4.5 mmol) from Example 11, part A, and triethylamine (0.76 mL, 5.5 mmol) in dichloromethane at 0° C. After warming to room temperature for 30 minutes, the reaction was quenched by addition of 1N HCl (30 mL). The product was extracted into dichloromethane (2×20 mL) and the combined organic layers were washed with saturated NaHCO3 (2×15 mL), dried (Na2SO4), and concentrated in vacuo. Flash chromatography on silica gel eluting with 15% i-propanol in ethylacetate in EtOAc gave the title compound (0.64 g) as an oil. |

The reaction was stirred at 0° C. for 20 minutes, then warmed to 65° C. for 2.5 hours. The reaction mixture was cooled to 0° C. and 6N HCl (4.0 ml) was added carefully. The solvent was removed in vacuo, and the residue was concentrated repeatedly from methanol (2×5 mL). The residue was dissolved in water (10 ml) and extracted with diethyl ether (3×5 ml). The aqueous layer was made basic to phenolphthalein with solid KOH and saturated with NaCl. The product was extracted into dichloromethane (5×20 ml), dried (Na2SO4) and concentrated to give the title compound (0.28 g). |
