  ABSTRACT: Hydrazone derivatives of vanillin are found to possess anti-bacterial activities. Based on higher bio-activity of hydrazones, new hydrazone derivatives were synthesized from Piperdine-4-carboxylicacid methyl ester (1). The compounds 1-pyrimidine-2-yl piperidine-4-carboxylicacid(4-hydroxy-3-methoxy benzylidine)-hy- drazide (10), 1-pyrimidine-2-yl piperidine-4-carboxylicacid (3,4-dimethoxy benzylidine) hydrazide (11), 1-pyrimidine-2-yl piperidine-4-carboxylicacid(4-butoxy-3-methoxy benzylidine)-hydrazide (12), 1-pyr- imidine-2-yl piperidine-4-carboxylicacid(3-methoxy-4(2-methoxy ethoxy) benzylidine)-hydrazide (13) were synthesized, purified and characterized by 1HNMR, 13CNMR, LCMS, FT-IR and HPLC techniques. The synthesized hydrazone derivatives were further checked for anti-bacterial activities by paper disc diffusion method against Pseudomonas aeruginosa and Staphylococcus aureus bacterial strains.
