実験手順

The crude (S)-methyl 2-(6-((2′,6′-dimethyl-4′-(piperidin-4-yloxy)biphenyl-3-yl)methoxy)-2,3-dihydrobenzofuran-3-yl)acetate 4a (31 mg, 0.06 mmol) was dissolved in 5 mL of methanol, followed by addition of 1M aqueous sodium hydroxide solution (0.6 mL, 0.62 mmol). The reaction solution was reacted for 2 hours. The resulting solution was concentrated under reduced pressure, mixed with 3 mL of water, 1M citric acid was added dropwise to adjust the pH to 5, and the solution was 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 (5)-2-(6-((2′,6′-dimethyl-4′-(piperidin-4-yloxy)biphenyl-3-yl)methoxy)-2,3-dihydrobenzofuran-3-yl)acetic acid 4 (31 mg, yield 100%) as a white solid.
