Procedure

To a solution of 4-fluoronaphthalene-1-carboxylic acid (153 mg, 0.801 mmol) in N,N-dimethylformamide (5 ml) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (154 g, 0.801 mmol) and 1-hydroxybenzotriazole monohydrate (123 mg, 0.801 mmol), and (1RS,2SR)-2-amino-1-(3-chlorophenyl)-3-[4-(2,2,3,3,3-pentafluoropropyl)phenyl]-1-propanol (0.30 g, 0.763 mmol) was finally added. The mixture was stirred at room temperature overnight. The mixture was diluted with ethyl acetate, washed with saturated aqueous sodium hydrogen carbonate solution, water and saturated brine, and dried over anhydrous magnesium sulfate. The mixture was filtered using a glass filter filled with silica gel, and the filtrate was washed with ethyl acetate and concentrated under reduced pressure. The residue was purified by recrystallization (hexane-ethyl acetate) to give N-[(1RS,2SR)-1-[4-(2,2,3,3,3-pentafluoropropyl)benzyl]-2-(3-chlorophenyl)-2-hydroxyethyl]-4-fluoro-1-naphthamide (0.284 g, 66%) as colorless crystals.
