We have reported some novel N’-[(1)-ethylidene]-2-(6-methyl-2-oxo-2H-chromen-4-yl) acetohydrazide synthesized by conventional method. The reaction of 2-(6-methyl-2-oxo-2H-chromen-4-yl)acetohydrazide with substituted benzaldehyde in methanol as a solvent yielded a series of (7a-l). The structures of all synthesized compounds are well characterized by Mass, FT-IR, 1H NMR, 13C NMR and elemental analysis. Moreover, all synthesized compounds were screened for in vitro antimicrobial activity against the gram positive (Staphylococcus aureus, Bacilluas subtilis) and gram negative (Escherichia coli, P. aeruginosa, K. pneunonae, Enterobacter) bacterial strain. In which some the compounds show potential inhibition against the test organisms.
