Procedure
A solution of 2.17 g of the 3-amino-4-chlorobenzo[d]isothiazole-1,1-dioxide prepared according to Example II and 2 ml of n-butylamine in 15 ml of dioxane was boiled for approx. 2 hours, ammonia escaping. After distilling off the solvent, the residue was stirred with water, sucked off, washed successively with water and petroleum ether and dried. The desired product was obtained in a yield of 2.4 g, melting-point 136°-138° C.
