Abstract
By condensation of 2-chlorobenzaldehyde, cyanothioacetamide, and 2-phenacylbenzothiazole in the presence of piperidine, we have synthesized piperidinium 5-(benzothiazol-2-yl)-4-(2-chlorophenyl)-3-cyano-6-hydroxy-6-phenyl-1,4,5,6-tetrahydropyridine-2-thiolate, based on which the corresponding partially hydrogenated 2-alkylthiopyridines have been obtained.
