実験手順

A mixture of 20 g p-isopropenylphenol, 1.1 equivalents ethylene carbonate, 0.02 equivalent potassium fluoride dihydrate, and 200 ml N,N-dimethylformamide (DMF) was heated at about 150° C. for about 1.5 hours. After removal of DMF under reduced pressure, the crude product was distilled. 2-(4-(1-Methylethenyl)phenoxy)ethanol, bp 143° C./7 torr, was obtained as a white solid in 69% yield.
