Benzimidazole derivatives are known to represent a class of medicinally important compounds which are extensively used in drug design and catalysis. A series of 2-substituted benzimidazole derivatives 10a-i was herein synthesized from the reaction of o-phenylenediamine with some amino acids using ameliorable pathway. The chemical structures of the synthesized compounds were confirmed by IR, UV, 1H-NMR, 13C-NMR, Mass spectral and analytical data. The compounds were investigated for their antimicrobial activity alongside gentamicin clinical standard. The results showed that this skeletal framework exhibited marked potency as antimicrobial agents. The most active compound was 1H-benzo[d]imidazol-2-yl)methanamine, 10a.
