実験手順
LiOH×H2O (131 mg) is added to a solution of methyl 2-((3S)-6-((1R)-4-(3-cyano-2-methylphenyl)-7-fluoro-2,3-dihydro-1H-inden-1-yloxy)-2,3-dihydrobenzofuran-3-yl)acetate (119 mg) in tetrahydrofuran (1 mL), water (1 mL) and methanol (1 mL) at room temperature. The mixture is stirred at room temperature for 12 hours. The mixture is concentrated, cooled to 0° C., diluted with water and acidified with 4 M aqueous HCl solution. The resulting mixture is extracted with dichloromethane. The organic phase is dried (MgSO4). The solvent is evaporated to give the title compound. Yield: 103 mg; LC (method 20): tR=6.30 min; Mass spectrum (ESI−): m/z=442 [M−H]−.
