  摘要：

  A method for the synthesis of methyl and ethyl 2-R-1-4-R-2-5-oxo-5,8-dihydropyrido[2,3-d]pyrimidine-7-carboxylates was proposed. The method is based on condensation of 2-R-1-6-R-2-5-acetyl-4-aminopyrimidines with ethyl oxalate in the presence of MeONa or EtONa. Products of the Friedlander self-condensation of the starting pyrimidines were also obtained.
