Procedure

A mixture of N-[3,5-bis(trifluoromethyl)phenyl]-2-hydroxy-5-iodobenzamide (4.75 g, 10 mmol), chloromethyl methyl ether (1.14 ml, 15 ml), potassium carbonate (2.76 g, 20 mmol) and acetone (50 mL) was refluxed for 8 hours. The reaction mixture was poured into diluted hydrochloric acid and extracted with ethyl acetate. After the organic layer was washed with water and brine, dried over anhydrous magnesium sulfate, the residue obtained by evaporation under reduced pressure was purified by chromatography on silica gel (hexane:ethyl acetate=3:1), and recrystallized (n-hexane/ethyl acetate) to give the title compound (3.96 g, 76.3%) as a white solid.
