C. 4-(2-Piperidin-1-yl-ethoxy)-phenylamine. To a solution of 1-[2-(4-nitro-phenoxy)-ethyl]-piperidine (300 mg, 1.20 mmol) in EtOH (50 mL) was added 10% Pd/C (50 mg). The mixture was placed on a Parr hydrogenator at 40 psi of H₂ for 30 min. The resultant mixture was filtered through diatomaceous earth, and the filtrate was concentrated to give a clear and colorless oil (264 mg, 100%). ¹H NMR (400 MHz, DMSO-d₆): 6.64 (d, J=8.7, 2H), 6.50 (d, J=8.0, 2H), 4.58 (s, 2H), 3.90 (t, J=6.0, 2H), 2.57 (t, J=6.0, 2H), 2.39 (s, 4H), 1.52-1.44 (m, 4H), 1.41-1.34 (m, 2H).
