実験手順

The crude (R)-tetrahydrofuran-3-yl methanesulfonate 1b (202 mg, 1.22 mmol), the crude 3-fluoro-3′-(hydroxymethyl)-2,6-dimethylbiphenyl-4-ol 19b (200 mg, 0.81 mmol) and cesium carbonate (527 mg, 1.62 mmol) were dissolved in 5 mL of N,N-dimethylformamide. The reaction mixture was heated to 80° C. and stirred for 12 hours. The resulting mixture was mixed with 20 mL of water and extracted with ethyl acetate (30 mL×2). The combined organic phase was washed with water (30 mL) and saturated sodium chloride solution (30 mL) successively, dried with anhydrous magnesium sulphate, and filtered. The filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography with elution system B to obtain the title compound (S)-(3′-fluoro-2′,6′-dimethyl-4′-((tetrahydrofuran-3-yl)oxy)biphenyl-3-yl)methanol 19c (130 mg, yield 50.8%) as a colorless slime.
