Reaction Steps

3-(Methoxycarbonyl)benzoic acid (500 mg, 2.78 mmol), methyl sulfonamide (264 mg, 2.78 mmol), HATU (1.06 g, 2.78 mmol), and diisopropylethylamine (1.45 mL, 8.33 mmol) were mixed in methylene chloride (20 mL) with stirring. The reaction was stirred for 20 hours, added sat'd ammonium chloride, and extracted with methylene chloride. The organic extracts were combined, dried over sodium sulfate and concentrated to give an amber oil which was purified over silica gel (1:1 hexanes/ethyl acetate to 100% ethyl acetate to 4:1 methylene chloride/methanol) to obtain methyl 3-(methylsulfonylcarbamoyl)benzoate (700 mg, 2.72 mmol, 97% yield). MS found: (M+H)+=258.07.
