Reaction Steps

To a solution of (1RS,2SR)-2-amino-1-(4-fluorophenyl)-3-(4-(trifluoromethyl)phenyl)-1-propanol (450 mg, 1.44 mmol) in acetonitrile (30 ml) were added N-t-butyloxycarbonyl-L-phenylalanine (382 mg, 1.44 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (413 mg, 2.15 mmol) and 1-hydroxy-1H-benzotriazole (220 mg, 1.44 mmol) and the mixture was stirred overnight at room temperature. The reaction solution was diluted with water (100 ml) and extracted with ethyl acetate (100 ml×2). The extract was washed with saturated brine, dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate). Recrystallization from ethyl acetate-hexane gave the title compound (315 mg, 39%).
