Reaction Conditions

Reaction Steps

To a tetrahydrofuran (1.5 ml) solution of methyl (6-(4-(ethylsulfonyl)phenoxy)-2-pyridin-2-yl-1H-benzimidazol-5-yl)(hydroxy)acetate (30 mg) obtained in Example 31 (step 2), added was lithiumaluminium hydride (10 mg), and the reaction liquid was stirred at 0° C. for 10 minutes. Sodium sulfate 10-hydrate was added to the reaction liquid, and stirred overnight at room temperature. Then, the residue was removed through filtration through Celite, and the solvent was evaporated away under reduced pressure. The resulting residue was purified through reversed-phase middle-pressure liquid chromatography (ODS-AS-360-CC (by YMC), mobile phase: water/acetonitrile/0.1% trifluoroacetic acid), and the resulting fraction was diluted with ethyl acetate, washed with aqueous saturated sodium bicarbonate and saturated saline water in that order, and dried with anhydrous sodium sulfate. The solvent was evaporated away under reduced pressure to obtain the entitled compound.
