New Heterocyclic Compounds Derived from 4,6-Diamino-3-cyano-2-methylthio-pyridine and their Biological Activity
Treatment of 4,6-diamino-3-cyano-2-methylthiopyridine (1) with aqueous KOH or hydrazine hydrate afforded the corresponding nicotinamide 2 and pyrazolo[3,4-b]pyridine 3, respectively. Reaction of compound 1 with bromine, sulfuryl chloride, formaldehyde, or aromatic diazonium salts gave 5- bromopyridine 4, 5-chloropyridine 5, dipyridylmethane 6, and azo dyes 7–10, respectively. Compound 1 reacted with diketones to yield the corresponding butenylamino derivative 11 and amides 12–15, ... إقراء المزيد
