Procedure

To a solution of (1RS,2SR)-2-amino-1-(4-fluorophenyl)-3-(3-(trifluoromethyl)phenyl)-1-propanol (450 mg, 1.44 mmol) in ethyl acetate (15 ml) were added 1-naphthoyl chloride (282 ml, 1.87 mmol) and saturated aqueous sodium hydrogen carbonate (15 ml) and the mixture was stirred at room temperature for 2 hrs. 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 recrystallized from ethyl acetate-hexane to give the title compound (582 mg, 87%).
