実験手順

To a solution of ethyl 3-[2-[2,4-dichlorophenyl)amino]-7-(diethylamino)-1H-benzimidazol-1-yl]propanoate (Reference Example 28; 100 mg, 0.223 mmol) in a mixture of tetrahydrofuran (2 mL) and methanol (1 mL) was added 1N sodium hydroxide solution (0.446 mL, 0.446 mmol) at 0° C. After the resultant mixture was stirred at room temperature for 1 hr, the mixture was neutralized with 1N hydrochloric acid and extracted with ethyl acetate. The combined organic layer was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with ethyl acetate to give the title compound as a solid (73.3 mg, 0.174 mmol, 78%).
