Reaction Steps

To a solution of methylamine hydrochloride (1.4 g) in pyridine (5 ml) was added 4-acetamidobenzenesulfonyl chloride (2.3 g), and the mixture was stirred at 50° C. for 2 hours. The residue obtained by an evaporation of pyridine under a reduced pressure was dissolved in methylene chloride (50 ml), washed with water, 1N hydrochloric acid, and saturated aqueous sodium chloride, and dried over anhydrous sodium sulfate. Evaporation of the solvent under a reduced pressure gave N-methyl-4-(acetamido)benzenesulfonamide (1.6 g).
