WebTsOH/graphite and N,N-dimethylaniline/graphite were found to be catalyst systems for condensation reaction of o-phenylendiamine with different aldehydes to form benzimidazole derivatives under mild and simple conditions.The graphite was easily recovered by a simple extraction and could be reused without decrease of activity in the presence of fresh TsOH … Web(7 ml) before p-TsOH (84.3 mg, 0.44 mmol) was added slowly into the solution at 0°C. Stirring was continued at room temperature. After 0.5 hour, water (10 ml) was added, and the organic layer was separated. The aqueous layer was extracted with Et 2O(2 5 ml), and the combined organic layers were washed with brine (10 ml), dried (MgSO
