Versuchsvorschrift
3-(4-Hydroxy-5-oxo-3-phenyl-2,5-dihydro-2-furyl)-propionic acid (100 mg) was dissolved in pyridine (2 ml), and acetic anhydride (1 ml) was added. The mixture was allowed to stand overnight. The excess reagent and solvent were removed by distillation under reduced pressure, and the residue was dried to give 3-(4-acetoxy-5-oxo-3-phenyl-2,5-dihydro-2-furyl)propionic acid (116 mg) as an oil.
