Reaction Steps

4-Chlorosulfonyl-3-methyl-benzoic acid (0.99 g, 4.2 mmol), methanamine (2.0 mL of 33% w/v, 21 mmol), and triethylamine (1.8 mL, 13 mmol) were stirred for 45 min at rt. The reaction mixture was evaporated and the resultant oil was partitioned between ethyl acetate and 1N HCl. The organics were separated and washed with another portion of 1N HCl and then brine. The organics were dried over sodium sulfate and evaporated to give 3-methyl-4-(methylsulfamoyl)benzoic acid (841 mg, 87%). ESI-MS m/z calc. 229.0, found 230.5 (M+1)+; Retention time: 0.64 minutes (3 min run).
