Procedure

A mixture of 1-[3-(4-nitro-phenoxy)-propyl]-piperidine (15.5 g, 58.6 mmol) and 10% Pd/C (12.5 g) in 150 mL of EtOH was placed under a balloon of H2. The mixture was stirred for 18 h. The catalyst was removed by suction filtration and the organics concentrated to give 4-(3-piperidin-1-yl-propoxy)-phenylamine as a yellowish oil.
