Methyl Isocyanate → HCID 13562979, compound

Participants

Reaction Steps

A solution of 3.7 g (0.55 mol) of methyl isocyanate in 30 ml of dioxane is added dropwise to 9.8 g (0.05 mol) of 3-hydrazino-2H,3H-1,2-benzisothiazole 1,1-dioxide in 100 ml of dioxane at room temperature. Stirring is continued for 1 hour, after which the product is filtered off under suction. 11.8 g (89% of theory) of 3-methylaminocarbonylhydrazino-1,2-benzisothiazole 1,1-dioxide of melting point 183° C. are obtained. The product can be recrystallized from ethanol.
