実験手順
To a cooled (0° C.), stirred solution of 3-benzyloxy-4-methoxybenzaldehyde (10 g) in MeOH (100 mL) was added hydrogen peroxide (5.5 mL of 30% aqueous) dropwise. After having been warmed to RT, concentrated sulfuric acid (1 mL) was added and the resulting solution was allowed to stir for 1.5 h. The reaction mixture was partitioned between ethyl ether/saturated aqueous sodium bicarbonate, another organic layer was dried over sodium sulfate and concentrated in vacuo to afford an oil. Flash chromatography (20% ethyl acetate/hexanes) afforded 3-benzyloxy-4-methoxyphenol (5.8 g).
