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.
