反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 2,2-difluoropropane-1,3-diamine (1.1 g, 10 mmol) and triethylamine (1.4 mL, 10 mol) in dichloromethane (15 mL) was added a solution of 2,4-dichloro-6-methylquinazoline (500 mg, 2.36 mmol) in dichloromethane (5 mL) dropwise. After being stirred at room temperature overnight, the resulting mixture was poured into water (50 mL) and extracted with dichloromethane (50 mL×2). The combined organic layers were washed with brine (50 mL), dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by flash column chromatography (eluting with 10-25% methanol in dichloromethane) to afford 41.8 mg of the desired product as a white solid (yield was 62%). MS obsd. (ESI+) [(M+H)+] 287. extracted with dichloromethane (50 mL×2) The combined organic layers were washed with brine (50 mL) dried over anhydrous sodium sulfate concentrated in vacuo The residue was purified by flash column chromatography (eluting with 10-25% methanol in dichloromethane)
