Procedure
4-(chlorosulfonyl)benzoic acid (0.5 g, 2.27 mmol) was treated with 4-chloro-N-methylaniline (963 mg, 6.80 mmol) using method A to give 4-(N-(4-chlorophenyl)-N-methylsulfamoyl)benzoic acid as a white solid. Yield: 406 mg (55%). 1H-NMR: 8.11 (d, J=8.5 Hz, 2H), 7.63 (d, J=8.5 Hz, 2H), 7.42 (d, J=8.5 Hz, 2H), 7.14 (d, J=8.5 Hz, 2H), 3.15 (s, 3H).
