Participants

Reaction Steps

To a solution of 4-methyl-3-(trifluoromethyl)phenol (5 g) and triethylamine (4.75 mL) in THF (40 mL) was added acetic anhydride (3.48 g), and the mixture was stirred at room temperature overnight. The reaction mixture was concentrated, saturated aqueous sodium hydrogen carbonate solution was added to the residue, and the mixture was extracted with ethyl acetate.
