実験手順

cis-N-(2-Amino-cyclohexyl)-2-methoxy-4,6-bis-trifluoromethyl-benzamide (intermediate H) (200 mg, 0.05 mmol) was dissolved in 10 mL methanol. Acetic acid (0.156 mg, 2.6 mmol) and cyclopropanecarboxaldehyde (73 mg, 1 mmol) were added and the reaction mixture was stirred 1 h at room temperature. Sodium triacetoxyborohydride (221 mg, 1 mmol) was added at stirring was continued at room temperature overnight. The mixture was extracted with 2N sodium carbonate solution and ethyl acetate. The combined organic phases were dried on sodium sulfate, filtered and evaporated. Crystallization with diisopropylether and a small amount of dichloromethane yielded cis-N-[2-(cyclopropylmethyl-amino)-cyclohexyl]-2-methoxy-4,6-bis-trifluoromethyl-benzamide as a white solid (83 mg, 36%), MS: m/e=439.3 [(M+H)+].
