Procedure

To the solution of 4-formylphenol acetate (6.0 g, 36.4 mmol) in 60 ml of methanol was added sodium boronhydride (1.50 g, 39.6 mmol) at 0° C. The resultant mixture was stirred for 1 hour, neutralized with acetic acid and then poured into water. The mixture was extracted three times with ether and the combined organic layer was dried over magnesium sulfate. After removal of solvent, the compound was purified by flash chromatography using heptane/ethyl acetate (80/20-70/30) as eluent in a yield of 41%.
