Ethyl 2-hydroxy-1-(2-thioxopyridin-1(2H)-yl)indolizin-3-carboxylate was formed along with ethyl (2-thioxopyridin-1(2H)-acetate from the reaction of 2-bromo-1-(ethoxycarbonylmethyl)pyridinium bromide with sodium sulfide. The structures of all compounds were confirmed by X-ray crystallography.How to Cite
