Synthesis, reactions and biological activity of 2-substituted 3-cyano-4,6-dimethylpyridine derivatives

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

The reaction of 2-chloro-4,6-dimethylpyridine-3-carbonitrile with hydrazine hydrate, hydroxylamine, and anthranilic acid afforded the corresponding pyrazolo, isoxazolo, and pyridoquinazoline derivatives. Alkylation of 2-mercapto-4,6-dimethylpyridine-3-carbonitrile with ethyl chloroacetate or phenacyl bromide followed by cyclization in NaOH gave thienopyridine derivatives. Diazotization of ethyl 3-amino-4,6-dimethylthiеno[2,3-b]pyridine-2-carboxylate followed by the reaction with thiourea, guanidine carbonate, and hydroxylamine hydrochloride gave the corresponding thienopyridine derivatives. The biological activity of some new compounds has been discussed.
