Abstract

A novel compound, 5,5'-(1,4-phenylenedimethylylidene)bis(1,3-diethyl-2-thioxodihydropyrimidine-4,6(1H,5H)-dione) (3) has been synthesized by condensation of 1,3-diethyl-2-thiobarbituric acid and terephthalaldehyde in anhydrous ethanol in the presence of pyridine. The structure of this compound was established by elemental analysis, IR, 1H-NMR, 13C-NMR and EI-MS spectral analysis.
Keywords: thiobarbituric acid; pyridine; Knoevenagel condensation thiobarbituric acid; pyridine; Knoevenagel condensation
