Reaction Steps

151 g (1.38 moles) of methanesulfonic acid methyl amide are dissolved in 500 ml of chlorobenzene, a solution of 215 g (1.52 moles) of chlorosulfonyl-isocyanate in 200 ml of chlorobenzene is added within 10 minutes at room temperature, the whole is subsequently heated at 120° - 125°C for 4 hours with agitation, and finally, the methanesulfonyl-methylamino-sulfonylisocyanate is isolated by distillation. The yield is 173 g (59 %), boiling point 94° - 98°C/0.1 torr.
