Reaction Steps

A mixture of 4-chloro-3-nitro-5-((1-(oxetan-3-yl)piperidin-4-yl)oxy)benzonitrile (430 mg, 1.272 mmol) and Pd/C (271 mg, 0.127 mmol) in methanol (20 mL) was hydrogenated at 20 PSI for 1.5 h. The reaction mixture was filtered through a pad of celite and the filtrate was concentrated in vacuo. The crude product was purified by flash chromatography on silica gel using an automated ISCO system (40 g gold column, eluting with 1-5% 2 N ammonia in methanol/dichloromethane). 3-amino-4-chloro-5-((1-(oxetan-3-yl)piperidin-4-yl)oxy)benzonitrile (50 mg) was obtained as a foaming solid.
