The trans-methyl 4-(((trans-2-phenylcyclopropyl)amino)methyl)cyclohexanecarboxylate (80 mg, 0.278 mmol) was stirred in a mixture of methanol (3 mL) and sodium hydroxide (3 ml, 3.00 mmol) for 1 hour at room temperature. The solution was then concentrated and purified by preparatory HPLC (5 to 50% AcCN:H2O with 0.1% formic acid modifier). The fractions were combined, 0.5 mL of 6 M HCl was added into each fraction and the product was evaporated. trans-4-(((trans-2-Phenylcyclopropyl)amino)methyl)cyclohexanecarboxylic acid (30 mg, 0.082 mmol, 29.6% yield) was isolated as white solid. 1H NMR (400 MHz, METHANOL-d4) δ 7.29-7.38 (m, 2H), 7.22-7.28 (m, 1H), 7.08-7.22 (m, 2H), 3.09 (d, J=7.07 Hz, 2H), 3.00 (dt, J=4.07, 7.77 Hz, 1H), 2.53 (ddd, J=3.79, 6.57, 10.36 Hz, 1H), 2.29 (tt, J=3.54, 12.25 Hz, 1H), 2.08 (dd, J=3.28, 13.39 Hz, 2H), 1.94 (dd, J=3.03, 13.14 Hz, 2H), 1.76 (ddd, J=4.29, 7.71, 11.24 Hz, 1H), 1.55 (ddd, J=4.55, 6.57, 10.61 Hz, 1H), 1.43-1.52 (m, 2H), 1.35-1.42 (m, 1H), 1.15 (qd, J=3.54, 12.72 Hz, 2H); LC-MS Rt=0.62 min; MS (ESI): 274.2 [M+H]+.
