A series of new N-substituted pyrazole-containing benzimidazoles was synthesized starting from 1,2-diaminobenzene and pyrazole-4-carbaldehyde in good yield. Antioxidant activity of all title compounds was assessed using 2,2-diphenyl-1-picrylhydrazyl and hydrogen peroxide assays. Some of the synthesized compounds having benzyl substituent at the imidazole nitrogen exhibited good activity in both assays.
