実験手順

Ammonium chloride (584 mg, 10.92 mmol) and zinc (356 mg, 5.46 mmol) were added to a solution of 4-chloro-3-((1-(3-methyloxetan-3-yl)piperidin-4-yl)oxy)-5-nitrobenzonitrile (96 mg, 0.273 mmol) in methanol (10 mL) and the reaction mixture was stirred at room temperature for 2 hours. The reaction mixture was filtered through celite and the filtrate was concentrated, the crude was purified by flash chromatography on silica gel using an automated ISCO system (loaded onto a 24 g dry column, 24 g column, eluting with 0-6% 2 N ammonia in methanol/dichloromethane). 3-amino-4-chloro-5-((1-(3-methyloxetan-3-yl)piperidin-4-yl)oxy)benzonitrile (87 mg) was obtained as a foaming solid.
