実験手順

A mixture of N-[3,5-bis(trifluoromethyl)phenyl]-2-methoxy-5-sulfamoyl-benzamide (442 mg, 1 mmol), 2,5-dimethoxytetrahydrofuran (159 mg, 1.2 mmol) and acetic acid (5 mL) was refluxed for 2 hours. After cooling, the reaction mixture was poured into water and extracted with ethyl acetate. After the organic layer was washed with water, saturated aqueous sodium hydrogen carbonate and brine, dried over anhydrous magnesium sulfate, the residue obtained by evaporating the solvent under reduced pressure was purified by chromatography on silica gel (n-hexane:ethyl acetate=3:2) to give the title compound (436.5 mg, 88.6%) as a white solid.
