The reactions of substituted anilines with chloroacetamide and sulfur in the presence of triethylamine afforded monothiooxamides. When treated with K(3)Fe(CN)(6), the latter underwent cyclization to form 2-carbamoylbenzothiazoles. The reactions were accompanied by the formation of the corresponding thiooxanilic acids, Which also Underwent cyclization to form benzothiazole-2-carboxylic acids.
