Versuchsvorschrift

A mixture of 2-acetyl-3-hydroxy-6-phenyl-4H-pyran-4-one (200 mg), potassium carbonate (150 mg), iodomethane (0.0600 mL) and DMF (5.0 mL) was stirred at room temperature overnight. The reaction mixture was diluted with water and the mixture was 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 (90.0 mg).
