Reaction Steps

A mixture of 2-(1-(4-(trifluoromethoxy)phenylsulfonyl)piperidin-4-yloxy)isoindoline-1,3-dione (390 mg, 0.82 mmol) and hydrazine monohydrate (0.044 ml, 0.90 mmol) in EtOH (4 ml) was stirred for 1 hour. The precipitated materials were filtered off and washed with EtOH (2 ml×2), then the filtrate was evaporated under reduced pressure to give O-(1-(4-(trifluoromethoxy)phenylsulfonyl)piperidin-4-yl)hydroxylamine (279 mg, 100%).
