Procedure

The solution of tert-butyl 2-(4-(((trans-2-phenylcyclopropyl)amino)methyl)piperidin-1-yl)acetate (40 mg, 0.116 mmol) in HCl-1 M (5 ml, 165 mmol) was stirred at the 50° C. for 24 hours. The solution was evaporated. The oil was suspended in acetonitrile, sonicated and filtered. 2-(4-(((trans-2-phenylcyclopropyl)amino)methyl)piperidin-1-yl)acetic acid (25 mg, 0.073 mmol, 63.0% yield) was isolated as a white solid. 1H NMR (400 MHz, METHANOL-d4) δ 7.30-7.38 (m, 2H), 7.17-7.29 (m, 3H), 4.13 (s, 2H), 3.74 (dd, J=1.52, 3.79 Hz, 2H), 3.11-3.29 (m, 4H), 3.05 (dt, J=4.14, 7.64 Hz, 1H), 2.61 (ddd, J=3.54, 6.63, 10.29 Hz, 1H), 2.15 (d, J=14.91 Hz, 3H), 1.73 (d, 2H), 1.62 (ddd, J=4.29, 6.63, 10.55 Hz, 1H), 1.37-1.49 (m, 1H); LC-MS Rt=0.39 min; MS (ESI): 289.3 [M+H]+.
