실험 절차

LiOH×H2O (3 mg) is added to a solution of methyl 2-((S)-6-((R)-4-(2,6-dimethyl-4-(methylcarbamoyl)phenyl)-7-fluoro-2,3-dihydro-1H-inden-1-yloxy)-2,3-dihydrobenzofuran-3-yl)acetate (20 mg) in ethanol (0.77 mL) and water (0.5 mL) and the mixture is stirred for 24 hours at room temperature. After concentration the mixture is diluted with water, acidified with aqueous citric acid solution and extracted with dichloromethane. The organic phase is dried (MgSO4) and the residue chromatographed on silica gel (cyclohexane/ethyl acetate 100:0→60:40) to give the title compound. Yield 11 mg, LC (method 20): tR=5.54 min; Mass spectrum (ESI+): m/z=490 [M+H]+.
