Procedure

To a solution of (1RS,2SR)-2-amino-3-[3-(neopentyloxy)phenyl]-1-(3-chlorophenyl)-1-propanol (0.30 g, 0.86 mmol) in N,N-dimethylformamide (5 ml) were added 4-fluoronaphthalene-1-carboxylic acid (0.17 g, 0.90 mmol) and 1-hydroxybenzotriazole monohydrate (0.138 g, 0.90 mmol), and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.173 g, 0.90 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, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by recrystallization (hexane-ethyl acetate) to give N-[(1RS,2SR)-1-[3-(neopentyloxy)benzyl]-2-(3-chlorophenyl)-2-hydroxyethyl]-4-fluoro-1-naphthamide (0.354 g, 79%) as colorless crystals.
