反応手順

A solution of 1-(4-nitro-phenyl)-piperidin-4-one (2.8 g, 12.7 mmol) in a mixture of 1:4 dioxane: methanol (100 mL) was hydrogenated over Raney nickel (1 g) under balloon pressure at ambient temperature overnight. The mixture was filtered through Celite and the filtrate was concentrated under vacuum. The resulting solid was washed with petroleum ether (2×10 mL) and dried to afford 1-(4-amino-phenyl)-piperidin-4-one (1.34 g, 55%).
