1 M aqueous NaOH solution (310 μL) is added to a solution of methyl 2-((S)-6-((R)-7-fluoro-4-(4-(3-hydroxy-3-methylbutyl)-2,6-dimethylphenyl)-2,3-dihydro-1H-inden-1-yloxy)-2,3-dihydrobenzofuran-3-yl)acetate (110 mg) in methanol (4 mL). The mixture is stirred at room temperature for 12 hours and at 50° C. for 2 days. 1 M aqueous NaOH solution (100 μL) is added and the mixture is stirred at 50° C. for 1 hour. Methanol is evaporated in vacuo, the residue is diluted with water and neutralized with 1 M aqueous HCl. The resulting mixture is extracted with ethyl acetate, and the combined organic phases are washed with brine and dried (MgSO4). The solvent is evaporated to give the title compound. Yield: 80 mg; LC (method 8): tR=0.59 min; Mass spectrum (ESI+): m/z=519 [M+H]+.
