Procedure

44 g (0.31 mole) of chlorosulfonyl-isocyanate are added to a solution of 50 g (0.29 mole) of benzenesulfonic acid methylamide in 150 ml of chlorobenzene, and the whole is heated at 120°C for 4 hours with agitation. The distillation yields 47 g (58 %) of phenylsulfonyl-methylaminosulfonylisocyanate having a boiling point of 125° -128°C/ 0.03 torr.
