Zusammenfassung:3-Cyano-5,4'-bipyridine-1'-oxides, 3-cyano-5,4'-bipyridines, 2-chloro-3-cyano-5,4'-bipyridine-1'-oxides, cardiotonic, vasodilatory. … 3-Cyano-5,4'-bipyridine-1'-oxides of the general formula I and their physiologically tolerable acid addition salts have useful cardiotonic and vasodilatory properties. They can be prepared by either … …  a) reacting 3-cyano-5,4'-bipyridines of the formula II with reagents suitable for the production of pyridine-N-oxides, preferably peracids or hydrogen superoxide, or …  b) reacting 2-chloro-3-cyano-5,4'-bipyridine-1'-oxides of the formula III with a compound of the formula IV and if desired converting the compounds of the formula I obtained into their acid addition salts with physiologically tolerable inorganic or organic acids. …
