6-Phenyl-2-(4-phenyl-5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)-4,5-dihydropyridazin-3(2H)-one

Abstract

6-Phenyl-2-(4-phenyl-5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)-4,5-dihydro-pyridazin-3(2H)-one 3 has been synthesized by a sequence of reactions starting from 6-oxo-3-phenyl-5,6-dihydropyridazine-1(4H)-carbohydrazide 1. The structure of the title compound 3 was established on the basis of IR, 1H-NMR, 13C-NMR and mass spectral data. © 2010 by the authors; licensee MDPI, Basel, Switzerland.
