Abstract: In the study, we have successfully synthesized N-((1H-benzo [d]imidazol-2-yl) methyl)-4-chloroaniline by the reaction of 4-chloroaniline with 2-(chloromethyl)-1H-benzo [d]imidazole. Thereafter novel derivative would be subjected to synthesize (1a&1b) by N-((1H-benzo [d]imidazol-2-yl) methyl)-4-methylaniline with 1, 2, 4-triazole and N-methyl-1H-1, 2, 4-triazol-3-amine These synthesized compounds (1a&1b) were characterized by FT-IR, 1H NMR and 13C spectroscopy, and the theoretical investigation of MEPs, HOMO, LUMO, and the energy gap of HOMO-LUMO were calculated by B3LYP/6-311G (d, p) method. The Synthesized compounds were evaluated for their antibacterial activities using agar diffusion methods respectively. A molecular docking study has supported the antimicrobial activity of the synthesized compounds.
