24.2 parts of 5-(4'-aminophenoxy)-benzisothiazole, 400 parts of toluene, 1 part of triethylamine and 11.4 parts of methyl isocyanate were heated at 80° C. for 12 hours, and the reaction mixture was then evaporated down under reduced pressure. 25 parts (85% of theory) of 5-(4'-methylaminocarbonylaminophenoxy)-benzisothiazole of melting point 178° C. were obtained.
