Abstract: The reactions of 2-chloronicotinoyl and 2,6-dimethyl-4-chloronicotinoyl isothiocyanates with thiols affording the corresponding 2-alkyl(aryl)thio-4-oxopyridothiazines, i.e. I and II, were studied. In the reaction of 2-chloronicotinoyl isothiocynate it was possible to isolate dithiocarbamates as intermediates. Halonicotinoyl isothiocyanates reacted similarly with NaHS to give 2-thio-4-oxopyridothiazines, i.e. III.
