실험 절차

To 4-{3-chloro-4-[2-(1,3-dimethyl-2-oxo-2,3-dihydro-1H-benzoimidazol-5-yl)-3,3,3-trifluoro-2-hydroxy-1-methyl-propyl]-phenoxy}-2-fluoro-benzoic acid methyl ester (400 mg) aqueous 1N LiOH (1.5 ml), MeOH (5 ml) and THF (10 ml) were added. The resulting solution was stirred for 1 h at room temperature. Volatile solvents were removed in vacuo. The residual aqueous solution was diluted with water (10 ml) and then acidified to pH 6 with 1 N aqueous HCl and extracted with EtOAc. The combined EtOAc layers were dried over Na2SO4 and concentrated to give the title compound (300 mg) as a white foam. MS (m/e)=551.2 [M+H+].
