Alok K. Pareek*, P. E. Joseph asnd Daya S. Seth

An efficient synthesis of some newly substituted pyrazoles (3a-3r) have been synthesized by the condensation reactions of malon (3-chloro-4-methoxy) phenyl anilic acid hydrazide (1a) with different substituted phenyl benzeneazo acetyl acetone hydrazones( 2a-2r) and glacial acetic acid being used as a catalyst in the all condensation reactions. The newly synthesized substituted pyrazoles structures have been established on the basis of their m.p, colour, analytical data, spectral analysis viz: I.R
