Versuchsvorschrift

To a solution of 1-cyclohexylethanone (95 mg, 0.751 mmol) in 1,2-dichloroethane (DCE) (40 mL) and acetic acid (0.052 mL, 0.901 mmol) was added [(trans)-2-phenylcyclopropyl]amine (100 mg, 0.751 mmol). The reaction mixture was stirred for 2 hour at room temperature, then sodium triacetoxyborohydride (477 mg, 2.252 mmol) was added and the reaction mixture was stirred 3 hours at room temperature. The reaction mixture was quenched with saturated NH4Cl. Water (20 mL) followed by dichloromethane (40 mL) were added. The layers were separated and the organic layer was washed with brine, dried over MgSO4, filtered and evaporated. The solid was suspended in diethylether, sonicated and filtered. trans-N-(1-Cyclohexylethyl)-2-phenylcyclopropanamine (48 mg, 0.187 mmol, 24.95% yield) was isolated as white solid. 1H NMR (400 MHz, DMSO-d6) δ 9.11-9.35 (m, 1H), 8.80-9.03 (m, 1H), 7.27-7.42 (m, 2H), 7.13-7.27 (m, 3H), 3.23 (br. s., 1H), 2.91 (d, J=2.78 Hz, 1H), 2.57 (ddd, J=3.54, 6.44, 9.98 Hz, 1H), 1.68-1.87 (m, 4H), 1.57-1.68 (m, 2H), 1.46-1.57 (m, 1H), 1.26-1.42 (m, 1H), 1.18-1.24 (m, 3H), 0.95-1.18 (m, 4H); LC-MS Rt=0.83 min; MS (ESI): 244.2 [M+H]+.
