Abstract

The title compound, 5-[(3,5-dimethyl-1-phenyl-1H-pyrazol-4-yl)methylene]-1,3-diethyl-2-thioxodihydropyrimidine-4,6(1H,5H)-dione, has been synthesized by condensation of 1,3-diethyl-2-thiobarbituric acid and 3,5-dimethyl-1-phenylpyrazole-4-carbaldehyde in ethanol in the presence of pyridine. The structure of this new compound was confirmed by elemental analysis, IR, 1H-NMR, 13C-NMR and EI-MS spectral analysis.
Keywords: thiobarbituric acid; Knoevenagel condensation; pyridine thiobarbituric acid; Knoevenagel condensation; pyridine
