Cyclohexanecarbonyl chloride → N-((1RS,2SR)-1-((4-fluorophenyl)methyl)-2-hydroxy-2-(4-(trifluoromethyl)phenyl)ethyl)cyclohexanecarboxamide

Participants

Reaction Steps

To a solution of (1RS,2SR)-2-amino-3-(4-fluorophenyl)-1-(4-(trifluoromethyl)phenyl)-1-propanol (450 mg, 1.44 mmol) in ethyl acetate (15 ml) were added cyclohexanecarbonyl chloride (288 ml, 2.15 mmol) and saturated aqueous sodium hydrogen carbonate (15 ml), and the mixture was stirred at room temperature for 3 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. Recrystallization of the residue from ethyl acetate-hexane gave the title compound (550 mg, 90%).
