실험 절차

The crude (S)-methyl 2-(6-((2′,6′-dimethyl-4′-((1-propionylazetidin-3-yl)oxy)biphenyl-3-yl)methoxy)-2,3-dihydrobenzofuran-3-yl)acetate 14d (45 mg, 0.09 mmol) was dissolved in 3 mL of methanol, followed by addition of 1M aqueous lithium hydroxide solution (0.5 mL, 0.50 mmol). The reaction solution was stirred for 3 hours. To the resulting solution, 1M hydrochloric acid was added dropwise to adjust the pH to 3, 3 mL of water were added, and then the solution was concentrated under reduced pressure and extracted with ethyl acetate (20 mL×2). The combined organic extracts were washed with saturated sodium chloride solution (30 mL), dried with anhydrous magnesium sulphate, and filtered. The filtrate was concentrated under reduced pressure to obtain the title compound (S)-2-(6-((2′,6′-dimethyl-4′-((1-propionylazetidin-3-yl)oxy)biphenyl-3-yl)methoxy)-2,3-dihydrobenzofuran-3-yl)acetic acid 14 (20 mg, yield 43.0%) as a yellow solid.
