Reaction Steps

To a mixture of 2-nitrobenzenesulfonyl chloride (5.09 g), N-methylethylamine (1.35 g) and chloroform (100 mL), triethylamine (4.11 mL) was added under ice cooling and stirred at room temperature for 5 hours. The reaction mixture was diluted with water and extracted with chloroform. The organic layer was washed sequentially with 1 M hydrochloric acid, saturated aqueous sodium hydrogen carbonate and saturated aqueous sodium chloride, and then dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to give N-ethyl-N-methyl-2-nitrobenzenesulfonamide (6.48 g) as a brown oil.
