We have developed a green procedure by using benzaldehyde and o-phenylene diamine as the model substrate, hetero polysaccharide pectin as a catalyst and water as a solvent. The generality and scope of this protocol was determined by synthesizing various derivatives of benzimidazole in good to excellent yield through this environment friendly, time and energy saving, green method.
