Acetonitrile → Benzenesulfonyl chloride, 4-chloro-3-nitro-

Participants

Reaction Steps

To a mixed solution consisting of 1,280 g of potassium 4-chloro-3 nitrobenzenesulfonate, 1,150 ml of acetonitrile, 250 ml of sulforan, and 30 ml of dimethylacetamide, was added dropwise 1,250 ml of phosphorous oxychloride, while maintaining the inner temperature between 60° C. and 70° C. The mixture was allowed to react at 73° C. for 3 hours. After allowing to cool, 400 ml of water was slowly added thereto, and the reaction mixture was poured into 5l of ice-water. The crystals thus precipitated were filtered, washed with water, and dried to obtain 1,060 g (84%) of the noted compound.
