실험 절차

To a solution of (1RS,2SR)-2-amino-3-[3-(1,1-difluoroethyl)phenyl]-1-(4-fluorophenyl)-1-propanol (0.40 g, 1.42 mmol) in acetonitrile (10 ml) were added 6,7-dihydro-5H-benzo[a]cycloheptene-1-carboxylic acid (0.28 g, 1.49 mmol) and 1-hydroxybenzotriazole monohydrate (0.22 g, 1.49 mmol), and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.27 g, 1.49 mmol) was finally added. The mixture was stirred overnight at room temperature. The mixture was diluted with ethyl acetate, washed with saturated aqueous sodium hydrogen carbonate, water and saturated brine, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=5:1, 2:1) and recrystallization (hexane-ethyl acetate) to give N-[(1RS,2SR)-1-[3-(1,1-difluoroethyl)benzyl]-2-(4-fluorophenyl)-2-hydroxyethyl]-6,7-dihydro-5H-benzo[a]cycloheptene-1-carboxamide (0.50 g, 78%) as colorless crystals.
