## Abstract We report the condensation of substituted 2‐aminopyridines 5 with β‐ketocarboxylic esters in polyphosphoric acid. In this reaction were obtained together with the target compounds, 4__H__‐pyrido[1,2‐__a__]pyrirnidin‐4‐ones 6 also the pyridin‐2‐ones 7. All the compounds 7 were tested for
