To a suspension of aluminium chloride (906 mg, 6.8 mmol) in methylene chloride (20 mL) is added 4-methyl-3-sulfamoyl-benzoyl chloride (1.1 g, 4.7 mmol) and anisole (1.1 g, 10.2 mmol). After the mixture is stirred at room temperature for 16 h, the reaction is quenched with 6 N HCl, and extracted with methylene chloride three times. The combined organic layers are washed with a saturated sodium chloride solution, dried with magnesium sulfate, and concentrated in vacuo. On standing, crystals form and trituration with diethyl ether and ethyl acetate provides 0.84 g (58% yield) of the title compound as a white solid. MS (m/z): 306 (M+1).
