Start heating 14:30 - IPC was taken after 18 h **IPC1 LCMS** , seems difficult to identify if any of the desired product was formed. Made an aqueous wash between citric acid/water and ethyl acetate, tedious separation, analysed the two phases IPC2 LCMS but still impossible to identify any product neither in the organic phase IPC3 LCMS. **No evidence of product formation.** The phases were discarded and the reaction judged as failed |

The reaction mixture was degassed for 10 minutes with nitrogen, and then Tris(dibenzylideneacetone)dipalladium(0) (217 mg, 0.24 mmol) was added. The reaction mixture was stirred at 105°C in an oil bath 12h. The solution was diluted with EtOAc and washed with saturated NaHCO3 solution, brine, dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. The crude material was loaded on a 80g silica gel column and purified on a Teledyne Isco instrument, eluting with 0% to 100% ethyl acetate in heptane to provide tert-butyl 4-(6-(trifluoromethyl)pyridin-2-yl)piperazine-1-carboxylate (811 mg, 51.7 %) as a solid. |
