실험 절차
To a solution of trans-2-phenylcyclopropanamine (80 mg, 0.601 mmol) in methanol (10 mL) was added trans-methyl 4-formylcyclohexanecarboxylate (102 mg, 0.601 mmol) and the reaction was heated to reflux for 2 minutes. After cooling back to the room temperature, sodium cyanoborohydride (75 mg, 1.201 mmol) was added to the reaction mixture and was stirred for 1 hour. Water (20 mL) was added. The reaction was concentrated and 20 mL of ethyl acetate was added. The layers were separated. The organic layer was washed with water, brine, and dried over MgSO4, filtered and evaporated. The resulting oil was purified on preperatory HPLC (10 to 60% AcCN:water with 0.1% formic acid as modifier). 0.5 mL of 6 M HCl was added into each fraction and the product was evaporated. trans-Methyl 4-(((trans-2-phenylcyclopropyl)amino)methyl)cyclohexanecarboxylate (95 mg, 0.250 mmol, 41.7% yield) was isolated as white solid. 1H NMR (400 MHz, METHANOL-d4) δ 7.29-7.38 (m, 2H), 7.22-7.29 (m, 1H), 7.11-7.22 (m, 2H), 3.68 (s, 3H), 3.09 (d, J=7.07 Hz, 2H), 2.99 (dt, J=4.11, 7.45 Hz, 1H), 2.49 (ddd, J=3.79, 6.57, 10.36 Hz, 1H), 2.35 (tt, J=3.63, 12.28 Hz, 1H), 2.07 (dd, J=3.54, 13.39 Hz, 2H), 1.93 (dd, J=3.28, 13.14 Hz, 2H), 1.66-1.83 (m, J=3.57, 3.57, 7.70, 7.70, 15.36 Hz, 1H), 1.50-1.58 (m, 1H), 1.36-1.50 (m, 3H), 1.15 (qd, J=3.54, 12.72 Hz, 2H); LC-MS Rt=0.83 min; MS (ESI): 288.2 [M++H]+.
