A mixture of [trans-2-phenylcyclopropyl]amine (540 mg, 4.05 mmol), 1-methyl-4-piperidinecarbaldehyde (506 mg, 3.98 mmol) and AcOH (l μL, 0.017 mmol) in chloroform (15 mL) was stirred at room temperature for 18 hours. Sodium triacetoxyborohydride (947 mg, 4.47 mmol) was added and stirring continued for 18 hours. Upon completion, saturated NaHCO3 was added to the reaction mixture and the mixture was extracted with THF—CHCl3 (2×50mL). The organics were combined, dried over Na2SO4 and concentrated. The residue was adsorbed onto silica and purified via column chromatography on the ISCO Companion (gradient 0-100% 80:20:2 [CHCl3/MeOH/NH4OH]/CHCl3; 40 g column) to obtain pure final compound (166 mg, 13% yield) as an off white solid: LC-MS (ES) m/z=245 (M+H)+, 1H NMR (400 MHz, DMSO-d6) δ ppm 7.17-7.27 (m, 2H), 7.06-7.15 (m, 1H), 6.97-7.06 (m, 2H), 2.64-2.77 (m, 2H), 2.41-2.49 (m, 2H), 2.27 (br. s., 1H), 2.18 (ddd, J=3.28, 4.23, 7.14 Hz, 1H), 2.08-2.15 (m, 3H), 1.70-1.83 (m, 2H), 1.57-1.70 (m, 2H), 1.30 (ddd, J=4.29, 7.26, 10.93 Hz, 1H), 1.01-1.16 (m, 2H), 0.86-0.98 (m, 2H).
