The target compounds N1-(2, 5-dichloro benzoyl)-3-methyl-4-(substituted phenyl hydrazono)-5-pyrazolone derivatives (2a-2t) have been synthesized by the condensation of different ethyl 2,3-dioxo butyrate-2-(substituted benzeneazo) phenyl hydrazone (1a-1t) with 2,5-dichloro phenyl hydrazine by using glacial acetic acid as a condensing agent. The structural assignment are based on their melting point, colour, elemental analysis, spectral data (IR) and chemical properties.
KEYWORDS:Pyrazolone; Subs. ethyl acetohydrazones; Subs. phenyl hydrazine; condensation; spectral data
