In this study, we aimed to develop new biologically active compounds with antibacterial properties. 4-amino-5-methyl-2H-1,2,4-triazol-3(4H)-one (1) was converted the corresponding Schiff bases (2) reaction a 4-anis aldehyde. Acetic acid ethyl esters containing [1,2,4] triazole ring (3) were synthesized by condensation of bromoacetate in basic media. The hydrazine hydrate led formation hydrazide...
