Procedure
To a solution of 1,2,3-triazole (66 mg) in DMF (0.6 mL) is added sodium hydride (25 mg). After gas evolution ceased, 2-[[3-(5-chloropent-1-ynyl)phenyl](1-methylpiperidin-4-yloxy)methyl]-1H-benzimidazole (50 mg) and a catalytic quantity of n-tetrabutylammonium iodide are added. After stirring overnight at room temperature, the solvent is removed under reduced pressure to dryness. The residue is purified by chromatography (dichloromethane/methanol/ammonia 90/10/1) to afford 2-{(1-methylpiperidin-4-yloxy)[3-(5-[1,2,3]triazol-2-yl-pent-1-ynyl)phenyl]methyl}-1H-benzimidazole.
