実験手順

(S)-(3′-Fluoro-2′,6′-dimethyl-4′-((tetrahydrofuran-3-yl)oxy)biphenyl-3-yl)methanol 19c (130 mg, 0.41 mmol), methyl (S)-2-(6-hydroxyl-2,3-dihydrobenzofuran-3-yl)acetate (85 mg, 0.41 mmol) and triphenylphosphine (161 mg, 0.62 mmol) were dissolved in 10 mL of dichloromethane, followed by addition of diisopropyl azodicarboxylate (125 mg, 0.62 mmol). The reaction solution was stirred for 2 hours. The resulting solution was concentrated under reduced pressure and the residue was purified by silica gel column chromatography with elution system B to obtain the title compound methyl 2-((S)-6-((3′-fluoro-2′,6′-dimethyl-4′-(((S)-tetrahydrofuran-3-yl)oxy)biphenyl-3-yl)methoxy)-2,3-dihydrobenzofuran-3-yl)acetate 19d (150 mg, yield 72.5%) as a colorless oil.
