To a solution of 2-nitrobenzene-1-sulfonyl chloride (30 g, 0.14 mol) in dichloromethane (500 mL) was slowly added a solution of methylamine in water (30%, 15.3 g) and triethylamine (38 mL, 0.27 mol) respectively. The mixture was stirred at room temperature for 1 hour and then evaporated. The residue was subjected to silica gel chromatography to afford the product N-methyl-2-nitrobenzenesulfonamide (26 g, yield 90%).
