Acetyl chloride → N-((1RS,2SR)-2-(4-fluorophenyl)-2-hydroxy-1-((4-(trifluoromethyl)phenyl)methyl)ethyl)-N-(1-naphthalenylmethyl)acetamide

To a solution of (1RS,2SR)-1-(4-fluorophenyl)-2-((1-naphthalenylmethyl)amino)-3-(4-(trifluoromethyl)phenyl)-1-propanol (100 mg, 0.22 mmol) in ethyl acetate (5 ml) were added acetyl chloride (225 ml, 3.3 mmol) and saturated aqueous sodium hydrogen carbonate (5 ml) and the mixture was stirred overnight at room temperature. The reaction solution was diluted with water (50 ml) and extracted with ethyl acetate (50 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 (hexane:ethyl acetate=1:1) to give the title compound (45 mg, 41%).
