Procedure
To a suspension of 1.06 g (5.31 mmol, 1.0 equiv.) of 4-amino-N-methylbenzenemethanesulfonamide in 20 mL of acetonitrile was added 0.862 g (5.31 mmol, 1.0 equiv.) of iodine monochloride. The reaction was stirred for 15 minutes at room temperature. The mixture was partitioned between 25 mL of ethyl acetate and 15 mL of 20% aqueous sodium thiosulfate. The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to yield an oil. The oil was filtered through a plug of silica gel using 40% ethyl acetate in hexane to yield 1.13 g (65%) of 4-amino-3-iodo-N-methylbenzenemethanesulfonamide
