Reaction Steps

Hydrazine monohydrate (0.272 ml, 5.61 mmol) was added to a solution of 2-{2-[1-(2-fluoro-4-nitrophenyl)piperidin-4-yl]ethyl}isoindoline-1,3-dione (compound of Reference Example 66; 0.745 g, 1.87 mmol) in ethanol (5 ml), and the mixture was stirred at 80° C. for 1 hour. Water was added to the reaction mixture and the mixture was extracted with dichloromethane. The organic layer was washed with saturated aqueous sodium hydrogencarbonate and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give the title compound (0.170 g, 34%) as a yellow solid.
