To a solution of N-[5-(p-fluorophenyl)-4-(tert-butoxycarbonyl)-4-azapentyl]phthalimide (2.1 g, 5.1 mmol) in methanol (20 ml) was added hydrazine monohydrate (0.4 ml) and the mixture was heated under reflux for 3 hours. After cooling, to the reaction mixture was added dichloromethane (50 ml) and then washed with aqueous ammonia (50 ml×2). The organic layer was dried over anhydrous potassium carbonate and the solvent was distilled off under reduced pressure to give 1.2 g of the title compound as a colorless oily substance. Yield=85%.
