3-[(1-Methylpiperidin-3-yl)oxy]benzonitrile (623 mg, 2.90 mmol) was dissolved (0.05 M) in NH3 in MeOH (58 ml). Hydrogenation was performed using a Raney-Ni 30×4 mm CatCart (H-Cube, 50 bar, 50° C., 1 ml/min). Evaporation in vacuo yielded the title compound as a colorless oil. Yield: 633 mg (99%). 1H NMR (400 MHz, CDCl3) δ 7.20 (t, 1H, J=7.9 Hz), 6.89-6.83 (m, 2H), 6.79 (dd, 1H, J=8.2 Hz, J=2.2 Hz), 4.37 (m, 1H, J=4.2 Hz), 3.80 (s, 2H), 2.91 (d, 1H), 2.62-2.54 (m, 1H), 2.28 (s, 3H), 2.13 (m, 2H), 1.97 (m, 1H), 1.86-1.76 (m, 1H), 1.69-1.54 (m, 3H), 1.52-1.40 (m, 1H).
