Several new synthesis of thieno[2,3-b]pyridine, pyrazolo[3,4-b]pyridine and pyridopyrazolo-1,2,4-triazine derivatives via the reactions of pyridinethiones with halogenated compounds, hydrazine hydrate and active methylene compounds.

The condensation of ethyl arylideneacetoacetate with cyanothioacetamide and of arylidenecyanothioacetamides with ethyl acetoacetate or of arylidenecyanothioacetamides with ethyl β-aminocrotonate gave 3-cyano-4-aryl-5-ethoxycarbonyl-6-methyl-3,4-dihydropyridine-2-thiones.PMR spectroscopy showed that the 3-cyano-4-aryl-3,4-dihydropyridine-2-thiones are formed as a mixture of cis and trans isomers.
