Abstract

1-acetyl-5-(substitutedphenyl)-{3-[4-(2-phenyl-4-p-hydroxybenzylidene-5-oxo-imidazol-1-yl)]phenyl}-4,5-dihydropyrazol have been prepared by the refluxation for three hours of 5-(substitutedphenyl)-[3-(4-{2-phenyl-4-(4-hydroxybenzylidene)-5-oxo-imidazol-1-yl})phenyl]-4,5-dihydropyrazol and Gly. aceticacid the intermediate A3 have been prepared by the refluxation for three hours of 4-(4-hydroxybenzylidene)-1-{4-[3-(substitutedphenyl)prop-2-enoyl]phenyl}-2-phenyl-imidazol-5-one with hydrazine hydrate in presence of ethanol the intermediate A2 synthesized by the condensation of  1-(4-acetylphenyl)-4-(4-hydroxybenzylidene)-2-phenyl-3,5-dihydro-imidazol-5-one with various aldehydes.
