Procedure

50.2 g (0.2 mol) of 5,6-dichloro-3-keto-2H,3H-1,2-benzisothiazole 1,1-dioxide in 200 ml of diethylene glycol are stirred with 35 g of hydrazine hydrate for 30 hours at 160° C. to 165° C. Working up analogously to Example 1 gives 31.7 g (63% of theory) of 5,6-dichloro-3-hydrazino-1,2-benzisothiazole 1,1-dioxide which decomposes at 276° C.
