Reaction Steps

To a mixture of 1-(2,6-difluorophenyl)-3-(4-(3,3-difluoropiperidin-4-yl)phenyl)-4-methoxy-1H-pyrazolo[4,3-c]pyridine (186 mg) and triethylamine (91.0 mg) in dichloromethane (4 mL) was added acetic anhydride (67.0 mg) under ice-cooling. The reaction mixture was stirred at room temperature for 2 hr, and diluted with dichloromethane. The organic layer was washed with water, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to give the title compound (200 mg).
