실험 절차

1 M aqueous NaOH solution (480 μL) is added to a solution of methyl 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)acetate (180 mg) in methanol (5 mL) at room temperature. The mixture is stirred at room temperature for 12 hours. The mixture is neutralized with 1 M aqueous HCl solution and partitioned between diethylether and brine. The organic phase is dried (MgSO4) and concentrated. The residue is chromatographed on silica gel (cyclohexane/ethyl acetate 60:40→10:90) to give the title compound. Yield: 80 mg; LC (method 4): tR=1.71 min; Mass spectrum (ESI+): m/z=539 [M+NH4]+.
