Reaction Steps
To a stirring solution of dimethylamine (180 mL, 40% in water, 1.57 mol) in methanol (180 mL) at 0° C., was slowly added 4-nitrobenzenesulfonyl chloride (69.5 g, 314 mmol). After complete addition, the cold bath was removed; and, after stirring overnight, the mixture was filtered and the precipitate was washed with water and dried in vacuo to give 68 g (94%) of tan solid.
