The reactions of substituted anilines with chloroacetamide and sulfur in the presence of triethylamine afforded monothiooxamides. When treated with K3Fe(CN)6, the latter underwent cyclization to form 2-carbamoyIbenzothiazoles. The reactions were accompanied by the formation of the corresponding thiooxanilic acids, which also underwent cyclization to form benzothiazole-2-carboxylic acids.
