Abstract A new efficient method of synthesizing 3-cyano-pyridine-2(1H)-ones containing variable substituents at position 4 and various aromatic substituents at position 1 of the pyridinone ring has been developed. The method is based on the reaction of ylidenecyanoacetic acid ethyl esters with dimethylformamide dimethyl acetal, the re-amination of obtained derivatives with several aromatic amines in
