3-[2-bromobenzylidenehydrazinocarbonyl-methyl]quinoxalin-2(1H)-one was cyclised to oxadiazolinyl derivative using acetic anhydride. Furthermore, 3-[5-sulfanylidene-4,5-dihydro-1,3,4-oxadiazol-2-yl)methyl]quinoxalin-2(1H)-one was employed as a precursor in the synthesis of some novel 2(1H)-quinoxalinones. Some of the newly prepared compounds were evaluated for in vitro antibacterial activity using ofloxacin as the
