Procedure

(5)-Methyl 2-(6-((2′,6′-dimethyl-4′-(piperidin-4-yloxy)biphenyl-3-yl)methoxy)-2,3-dihydrobenzofuran-3-yl)acetate 4a (26 mg, 0.05 mmol) was dissolved in 5 mL of dichloromethane, followed by addition of methanesulfonyl chloride (6 mg, 0.05 mmol) and triethylamine (15 mg, 0.15 mmol). The reaction solution was reacted for 1 hour. The resulting solution was mixed with 10 mL of water, and concentrated under reduced pressure to obtain the crude title compound (S)-methyl 2-(6-((2′,6′-dimethyl-4′-((1-(methylsulfonyl)piperidin-4-yl)oxy)biphenyl-3-yl)methoxy)-2,3-dihydrobenzofuran-3-yl)acetate 5a (40 mg) as a white solid, which was directly used in the next step without further purification.
