Procedure

A mixture of [trans-2-phenylcyclopropyl]amine (116 mg, 0.871 mmol), 1,1-dimethylethyl 4-acetyl-1-piperidinecarboxylate (110 mg, 0.484 mmol) and AcOH (1 μL, 0.017 mmol) in Chloroform (10 mL) was stirred at room temperature for 18 hours. Sodium triacetoxyborohydride (196 mg, 0.925 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 CHCl3 (2×50 mL). 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; 12 g column) to yield the desired product. This was further purified via reverse phase column chromatography on Gilson (C18 column: 0.1% Formic acid H2O/CH3CN, 95-5%) to obtain pure the pure title compound (67 mg, 22% yield) as a colorless oil: LC-MS (ES) m/z=345 (M+H)+.
