実験手順

Diisopropylethylamine (1.432 ml, 8.20 mmol) and (2R,6R)-2,6-dimethylmorpholine (1.027 ml, 8.20 mmol) were added to a solution of 3-(3,3-difluoroazetidine-1-carbonyl)-6,7-difluorobenzo[d]isoxazole-5-carbaldehyde (Intermediate 241, 1.906 g, 6.31 mmol) in acetonitrile (50 ml). The reaction was stirred at reflux for 20 hours. The reaction was cooled to room temp, diluted with water and brine and extracted twice with ethyl acetate. The organic layers were combined, dried over MgSO4 and concentrated. The residue was purified by silica gel column chromatography using a gradient of DCM to ethyl acetate. Fractions were combined and concentrated to give the title compound.
