実験手順
Methyl 3-({6-[(3-chloropyridin-2-yl)oxy]-1-methyl-1H-benzimidazol-2-yl}methoxy)benzoate produced in Example (1f) (2.46 g, 5.8 mmol), a 2 M sodium hydroxide aqueous solution (10 mL) and 1,4-dioxane (20 mL) were stirred at 80° C. for two hours. After leaving to cool, the reaction mixture was concentrated and water (100 mL) was added. This aqueous solution was neutralized by adding 1 M hydrochloric acid and the precipitated solid was collected by filtration to obtain the title compound (1.59 g, 67%) as a white solid.
