Reaction Steps

The 1-[2-[2-(4-isobutyloxycarbonylbenzyl)phenoxy]ethyl]-4-(2-hydroxymethyl-1H-benzimidazol-1-yl)piperidine (49 mg) obtained in Example 103 was dissolved in methanol (0.5 ml), added with 1 N aqueous sodium hydroxide (0.18 ml) and stirred at 50° C. for 2.5 hours. After the reaction mixture was added with 1 N aqueous hydrochloric acid (0.72 ml), the solvent was evaporated under reduced pressure. The residue was purified by LH-20 column chromatography (elution solvent: dichloromethane:methanol=1:1) to obtain 48.3 mg of the title compound as hydrochloride. Yield: 100%.
