✦ Synopsis

The interaction of I-(3-cyano-5-nitropyridyl*2)pyridinium salts with different nucleophilic reagents yields 2-substitnted 3 -c.va no-5 -rot ro~.ridine, including 2-polyenamino derivatives. 3-Nitro-5(H)-5imiuodipyridoll.2-a:3,2-elpyrimidine hydrochloride is synthesized by the reaction of 2.-chloro-3-cyano-5nilropyridine with 2-aminopyridine.
