Synthesis and spectral studies of some new pyrazoline compounds

3-{4-[5-(substitutedphenyl)-4,5-dihydro-pyrazol-3-yl]phenyl}-6-bromo-2-thioxo-2,3-dihydro quinazolin-4-one have been prepared by the refluxation for three hours of 3-{4-[3-substituted phenyl)prop-2-enoyl] phenyl}-6-bromo-2- thioxo-2,3 dihydroquinazolin-4-one in presence of ethanol & hydrazine hydrate. After Synthesis Compounds Were Characterized by Chemical as Instrumental Methods. Like Elemental, IR and NMR.
