5 parts of gaseous dimethylamine were passed into 30.3 parts of 5-(2'-chloro-4'-isocyanatophenoxy)-benzisothiazole and 300 parts of diethyl ether at from 20° to 30° C., the mixture was stirred for 12 hours at this temperature and the resulting precipitate was then isolated and dried. 27.5 parts (70% of theory) of 5-(2'-chloro-4'-dimethylaminocarbonylaminophenoxy)-benzisothiazole of melting point 149° C. were obtained.
