An efficient and green one-Pot Synthesis of 8-(3-Bromo-4,5-Dimethoxyphenyl)-6-(Nitrophenyl)-4-Imino-2-(Methylsulfanyl)-4H-Pyrido [1,2-a] Pyrimidine-3,9-Dicarbonitrile

Abstract: A mixture of 2-amino-4-(3-bromo-4,5-dimethoxyphenyl)-6-(4-nitrophenyl)pyridine-3-carbonitrile and bis(methylthio)methylene malononitrile (BMMM) was combined with banana peel powder (1gm) in DMF as the solvent and refluxed for approximately 4-6 hours to obtain the pyrido-pyrimidine nucleus (yield: 77%). The structures of the synthesized compounds were confirmed through IR, 1H NMR, and mass spectral analyses
