Abstract

The condensation of acetaldehyde with cyanothioacetamide and ethyl benzoylacetate in the presence of N-methylmorpholine leads to the formation of 3-cyano-5-ethoxycarbonyl-4-methyl-6-phenylpyridine-2(1H)-thione. Alkylation of the last afforded the corresponding substituted 2-alkythiopyridines.
