反应详情

In acetonitrile (4 mL) was suspended 2,2-dimethyl-3-(4-{5-[5-(2,2,2-trifluoro-1,1-dimethylethyl)-1H-imidazol-2-yl]pyridin-2-yl}phenoxy)propanoic acid (175 mg), and 2N aqueous sodium hydroxide solution (391 μL) was added dropwise to the suspension. After adding acetonitrile (1 mL), the reaction mixture was stirred at room temperature overnight. Methanol was added until the reaction mixture became uniform solution, and tar-state insoluble material was separated by filtration. The filtrate was concentrated under reduced pressure, and the obtained solid residue was pulverized by ether, collected by filtration, washed with ether, and dried at room temperature in vacuum to obtain sodium 2,2-dimethyl-3-(4-{5-[5-(2,2,2-trifluoro-1,1-dimethylethyl)-1H-imidazol-2-yl]pyridin-2-yl}phenoxy)propanoate (174 mg).
