実験手順
Methyl 3-hydroxy-2-methylene-3-phenylpropionate (1.7836 g, 9.279 mmols) was dissolved in 1.75 ml (18.55 mmols) of acetic anhydride, and 0.03 ml of sulfuric acid were added thereto. The mixture was stirred at 100° C. for 4 hours. After the completion of the reaction, the reaction solution was concentrated under reduced pressure to obtain 2.1917 g of a crude product of the above title compound.
