Abstract:Four hydrazones 3(a-d) are synthesized from following three steps: firstly ethyl 2-[4-bi- (4- fluorophenyl)-methyl- piperazin - 1 - yl]acetate (1) is synthesized by the reaction of l-[bi-(4-fluorophenyl)methyl]-piperazine with ethyl chloroacetate in acetone under microwave irradiation. Then treatment of the compoun (1) with hydrazine to give 2-[4 - bi - (4 - fluorophenyl) -methylpiperazin-1-yl] Acteyl Hydrazine(2). Finally compound (2) reacted with aromatic aldehydes and ketones under microwave irradiation yielded the corresponding compounds 2-[4-bi-(4-fluorophenyl)-methylpiperazin-1-yl] Acteyl Hydrazones 3(a-d) in good yields. The structures of four new compounds are confirmed by IR, ^1H NMR, MS spectra and elemental analysis.
Keywords:1- piperazine  hydrazone  organic synthesie  microwave irradiation
