Abstract: Synthesis of 3-substituted 1H-4-imino-5-(4-methoxyphenyl)-7-phenylpyrido[2,3-d]pyrimidine-2-thiones, 3-substituted 3H-2-thioxo-5-(4-methoxyphenyl)-7-phenylpyrido[2,3-d]pyrimidin-4-ones, 3-substituted ЗH-2-methylmercapto-5-(4-methoxyphenyl)-7-phenylpyrido[2,3-d]pyrimidin-4-ones, and 3-substituted 3H-2-(morpholino/piperidino)-5-(4-methoxyphenyl)-7-phenylpyrido[2,3-d]pyrimidin-4-ones has been reported. The structures of newly synthesized compounds have been established on the basis of the spectral data.
