実験手順

A mixture of 5,6-dichlorobenzimidazole (94 mg, 0.50 mmol), 4-fluorobenzaldehyde (0.064 mL, 0.60 mmol), and potassium carbonate (83 mg, 0.60 mmol) in dimethylsulfoxide (3 mL) was heated at 100° C. for 3 h. The mixture was cooled to room temperature, and water was added. The precipitated product was collected by filtration and washed with water and ethanol to afford 5,6-dicloro-1-(4-formylphenyl)benzimidazole (90 mg, 62%).
