The crude (S)-tetrahydrofuran-3-yl methanesulfonate 2b (522 mg, 3.14 mmol), 3′-(hydroxymethyl)-2,6-dimethylbiphenyl-4-ol (714 mg, 3.13 mmol, prepared by a method disclosed in Chinese patent application CN101616913) and cesium carbonate (3.10 g, 9.39 mmol) were dissolved in 30 mL of N,N-dimethylformamide. The reaction mixture was heated to 80° C. and stirred for 12 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 (R)-(2′, 6′-dimethyl-4′-((tetrahydrofuran-3-yl)oxy)biphenyl-3-yl)methanol 2c (540 mg, yield 58.0%) as a colorless oil.
