Participants

Reaction Steps

To a solution of 2-[(1-methylpiperidin-4-yl)oxy]-1H-isoindole-1,3(2H)-dione 49 (1.18 g, 4.53 mmol) in a mixture of ethanol (3 mL) and DCM (18 mL) was added hydrazine hydrate (0.268 g, 4.53 mmol). The reaction mixture was stirred at room temperature for 4.5 h. Precipitate was filtered off. The filtrate was evaporated and sonicated in ethyl acetate (20 mL). Solid was filtered off and filtrate was evaporated to give the residue which was subjected to chromatography to give 50 (0.15 g, 25%) as a colorless oil.
