3-Cyanopyridines containing an acetyl, ester, nitro, or cyano group in the 5-position were synthesized via various versions of the Hantzsch reaction. Recyclization of quaternary pyridinium salts by the action of aqueous-alcoholic alkali afforded 2-methylaminopyridine derivatives and 6-methylamino-3-nitro-2,4-diphenylbenzonitrile.
