Reaction of isonicotinaldehyde with 2-cyanoacetohydrazide afforded ( E )-2-cyano- N' -(pyridin-4-ylmethylene)acetohydrazide ( 1 ). Compound 1 was used as the precursor for the synthesis of novelpyridinederivatives by reaction with different arylidene malononitriles, malononitrile and acetylacetone to give pyridinederivatives 5a – e , 6 and 7 , respectively. 4,4'-Bipyridine derivatives 9a – d were
