To a stirring suspension of sodium hydride (2.25 g of 60% in oil) in DMF (10 mL) at 0° a solution of 2-Fluoro-6-(1H-imidazol-2-yl)-pyridine (7.7 g, 47.2 mmol) in DMF (20 mL) is added. After stirring for 5 minutes, a solution of 1-n-Propyl-2-chloromethyl-5-cyanobenzimidazole (11 g, 47.2 mmol) and sodium iodide (20 mg) in DMF (80 mL) is added. The reaction mixture is stirred for 6 h, gradually warmed to room temperature. The reaction mixture is cooled, water added, the solid collected, rinsed with water and dried to afford the title compound, 1-Propyl-2-{[2-(2-fluoropyrid-6-yl)-1H-imidazol-1-yl]methyl}-5-cyano-1H-benzimidazole.
