Procedure

30 mg of potassium carbonate and 0.014 ml of methyl iodide were added to a dimethylformamide (1.0 ml) solution of 78 mg of 4-(4-fluoro-phenoxy)-6-(pyridin-3-yloxy)-1H-benzimidazole-2-thiol produced in Example 115, and the reaction liquid was stirred at 0° C. for 30 minutes. The reaction liquid was diluted with ethyl acetate, washed with water and saturated saline in order, and dried with anhydrous magnesium sulfate. The solvent was evaporated away under reduced pressure to obtain the entitled compound.
