実験手順

To a solution of 2-((3S)-6-((1R)-4-(2,6-dimethyl-4-(2-(methylsulfinyl)ethoxy)phenyl)-7-fluoro-2,3-dihydro-1H-inden-1-yloxy)-2,3-dihydrobenzofuran-3-yl)acetic acid (70 mg) in methanol (1.5 mL) and water (0.75 mL) is added potassium peroxomonoslufate (Oxone®) (150 mg). The mixture is stirred for 3 hour at room temperature and then potassium peroxomonoslufate (Oxone®) (80 mg) is added. After stirring for 12 hours at room temperature the mixture is partitioned between ethyl acetate and water. The organic phase is dried (MgSO4) and concentrated. The residue is chromatographed on silica gel (cyclohexane/ethyl acetate 50:50→0:100). The product thus obtained is dissolved in acetonitrile/water (1:1) and lyophilized to give the title compound. Yield: 7 mg; LC (method 4): tR=1.71 min; Mass spectrum (ESI+): m/z=555 [M+H]+.
