The crude (4′-(benzyloxy)-4-fluoro-2′,6′-dimethylbiphenyl-3-yl)methanol 18b (370 mg, 1.10 mmol) was dissolved in 5 mL of methanol, followed by addition of Pd/C (40 mg, 10%) under hydrogen atomosphere. The reaction mixture was stirred for 12 hours. The resulting mixture was filtered. The filtrate was concentrated under reduced pressure and the residue was purified by silica gel column chromatography with elution system B to obtain the title compound 4′-fluoro-3′-(hydroxymethyl)-2,6-dimethylbiphenyl-4-ol 18c (225 mg, yield 83.3%) as a white solid.
