Reaction Steps

To a suspension of methoxylamine hydrochloride (0.93 g (11.1 mmol)) in pyridine (5.0 ml), 3,4-dichlorobenzenesulfonyl chloride (2.73 g (11.1 mmol)) was added with stirring under cooling with ice and the resulting mixture was stirred for one hour under cooling with ice, and at room temperature for 18 hours. Water (50.0 ml) was then added to the reaction mixture to bring about separation of crystals. The crystals were filtered and washed with water to give 2.69 g (95%) of 3,4-dichloro-N-methoxybenzenesulfonamide as pale yellow crystals.
