실험 절차

2-[4-Cyano-4-(4-nitro-phenyl)-piperidin-1-yl]-acetamide (0.644 g, 2.23 mmol) was shaken over 5% Platinum on Carbon, Sulfided (0.5%) (94 mg, 0.024 mmol) in Methanol (10.0 mL) under an atmosphere of Hydrogen (40 psi) for 5 h. The precipitate was solubilized in DCM and then filtered to remove catalyst, washing with DCM. Conc. in vacuo to give 2-[4-(4-Amino-phenyl)-4-cyano-piperidin-1-yl]-acetamide (0.570 g; Yield=98.8) as an off white solid. 1H-NMR (DMSO-d6): 7.29 (s, 1H), 7.14 (m, 3H), 6.58 (d, 2H, J=8.4 Hz), 5.17 (s, 2H), 3.17 (d, 1H, J=5.2 Hz), 2.92 (s, 2H), 2.90 (m, 2H), 2.39 (m, 2H), 2.00 (m, 4H).
