Reaction Steps

To a solution of (S)-2-phenyl propylamine (0.5 g, 3.7 mmol) in dry dichloromethane was added acetic acid followed by 2-chloro-3-trifluoromethylbenzaldehyde (1.1 g, 5.5 mmol) and sodium triacetoxyborohydride (1.5 g, 7.4 mmol). After the resulting mixture was stirred for 1.5 h at RT water was added to quench the reaction. The aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate, and concentrated in vacuo. The crude mixture was purified by column chromatograph (Ethyl acetate:Hexane/25:75) to give the title compound as an oil (0.55 g, 45%). MS (ESI) 327.6 (M+H)+.
