Versuchsvorschrift

To the solution of 4-hydroxybenzaldehyde (10.0 g, 81.9 mmol) in 150 ml of pyridine was added acetic anhydride (60 ml). The resultant mixture was stirred at room temperature for 2 hours. After removal of the solvent, the compound was purified by flash chromatography using heptane/methylene chloride/ethyl acetate (20/20/10) as eluent in a yield of 93%.
