Versuchsvorschrift

A mixture of 2-acetyl-3-hydroxy-6-phenyl-4H-pyran-4-one (0.53 g), potassium carbonate (0.40 g), benzyl bromide (0.27 mL) and DMF (10 mL) was stirred at room temperature for 2 hr. The reaction mixture was diluted with water, and extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (0.18 g).
