Abstract :A novel synthesis of N-Phenyl aminopyridone via the reaction of cyanoacetphenylhydrazide and ylidene malononitrile is reported. in the last few years we have been interested in development of new procedures for synthesis of polyfunctionally substituted azoles and azines of potential synthetic and biological interest[l-3]. In continuat- ion of this work ve investigated the reactivity of cyanoacetphenylhyd- drazide I with some cinnamonitrile derivatives. Soto et al [4] have rc- cently reported that the reaction of benzylidene cinnamonitrile 2 b with cyanoacethydrazide affords N-aminopyridine derivative, formed via Michael addition, cyclization and oxidation of the formed hydropyridine derivative.Keywords : NITRILES IN HETEROCYCLIC, SYNTHESIS, N-AMINOPYRIDINES
