실험 절차

A solution of (1R,2S)-2-phenylcyclopropanamine (1.051 g, 7.89 mmol) and ethyl 4-(3-(4-formylpiperidin-1-yl)propyl)benzoate (1.9 g, 6.26 mmol) in methanol (50 mL) was heated to reflux for 5 minutes. The reaction was cooled to room temperature and sodium cyanoborohydride (0.590 g, 9.39 mmol) was added. The reaction was stirred at room temperature for 16 hours. After concentrating, dichloromethane was added and the solution was washed with water followed by brine and dried over MgSO4, filtered and concentrated. The residue was purified via Biotage (0% to 100% EtOAc:Hex; to get off impurity then 0% to 20% MeOH:DCM to get off product 50 g-HP—silica gel column) to yield 1.18 g 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 0.90-1.18 (m, 2H), 1.20-1.36 (m, 2H), 1.40 (t, J=7.07 Hz, 4H), 1.66-1.80 (m, 2H), 1.81-2.02 (m, 5H), 2.24-2.45 (m, 3H), 2.56-2.79 (m, 4H), 2.95 (d, J=10.86 Hz, 2H), 4.38 (q, J=7.24 Hz, 2H), 6.99-7.10 (m, 2H), 7.10-7.20 (m, 1H), 7.21-7.38 (m, 5H), 7.97 (d, 2H) MS (ES); [M+H]+421.3
