Procedimiento

A solution of 4,4′-dihydroxystilbene (250 mg, 1.178 mmol) in MeOH (10 mL) and EtOAc (2 mL) containing 5% Pd-C (120 mg) was stirred under an atmosphere of hydrogen for 2 h. The catalyst was removed by filtration and the filtrate was concentrated. Chromatography purification of the crude product on silica gel (hexane-EtOAc 3:1, 2;1) provided 245 mg of 4-[4-Hydroxy-phenethyl]-phenol (97%) as a white solid. MS (ES) m/z: 213.05 (M−1).
