실험 절차

To a solution of N-[4-(trans-2-aminocyclopropyl)phenyl]-3-(trifluoromethyl)benzamide hydrochloride (80 mg) in methanol (3 mL)/THF (3 mL) were added 1-methylpiperidin-4-one (33.0 mg) and sodium hydrogen carbonate (37.7 mg). The mixture was stirred at 60° C. for 2 hr, and ice-cooled to 0° C. and sodium borohydride (17.0 mg) was added. The mixture was stirred at room temperature for 2 hr, and ice-cooled to 0° C., and saturated aqueous sodium hydrogen carbonate solution was added. The mixture was extracted with ethyl acetate, and the extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate, ethyl acetate/methanol). 10% Hydrochloric acid methanol solution was added and the solvent was evaporated under reduced pressure. The residue was recrystallized from methanol/diisopropyl ether to give the title compound (40 mg).
