실험 절차

A mixture of [trans-2-phenylcyclopropyl]amine (496 mg, 3.72 mmol), 1,1-dimethylethyl 4-formylhexahydro-1H-azepine-1-carboxylate (871 mg, 3.83 mmol) and AcOH (l μL, 0.017 mmol) in chloroform (5 mL) was stirred at room temperature for 18 hours. Sodium triacetoxyborohydride (950 mg, 4.48 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 (2×50 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 0-40% 80:20:2 [CHCl3/MeOH/NH4OH]/CHCl3; 40 g column) to afford the desired product (168 mg, 12%) as a pale yellow oil LC-MS (ES) m/z=345 (M+H)+.
