実験手順

3-(4-Hydroxy-5-oxo-3-phenyl-2,5-dihydro-2-furyl)propionic acid (100 mg) was dissolved in methanol (2 ml), and a solution of diazomethane in ether was added thereto until the yellow color did not vanish any longer. The mixture was allowed to stand at room temperature overnight. The solvent was then distilled off to give methyl 3-(4-methoxy-5-oxo-3-phenyl-2,5-dihydro-2-furyl)propionate (110 mg).
