Reaction Steps

102.8 g (0.865 mol) of thionyl chloride were added to 71.8 g (0.288 mol) of 2-(ethylsulfonyl)benzenesulfonamide in 500 ml of 1,2-dichloroethane in the course of 30 minutes while stirring at from 70° to 80° C., and the refluxed mixture was stirred for 2.5 hours. After the mixture had been cooled to 50° C., 2 ml of pyridine were added and gaseous phosgene was passed into the refluxed mixture in the course of 5 hours while stirring. Evaporating down gave 84.1 g of the title compound, which was taken up directly in 1,2-dichloroethane for storage.
