Reaction Steps

2-((S)-6-((4-(Benzyloxy)-2′,6′-dimethyl-4′-(((R)-tetrahydrofuran-3-yl)oxy)biphenyl-3-yl)methoxy)-2,3-dihydrobenzofuran-3-yl)acetic acid 36c (152 mg, 0.26 mmol) was dissolved in 5 mL of ethyl acetate, followed by addition of Pd/C (30 mg, 10%). The reaction solution was stirred for 12 hours. The resulting solution was filtered. The filtrate was concentrated under reduced pressure and the residue was purified by TLC with elution system A to obtain the crude title compound 2-((S)-6-((4-hydroxy-2′,6′-dimethyl-4′-(((R)-tetrahydrofuran-3-yl)oxy)biphenyl-3-yl)methoxy)-2,3-dihydrobenzofuran-3-yl)acetic acid 36 (18 mg, yield 14.1%) as a white solid.
