反応手順
5.6 g (0.1 mole) potassium hydroxide in 10 ml water was added to a cooled solution of 13.8 g (0.1 mole) p-hydroxyphenethyl alcohol in 50 ml tetrahydrofuran. 10.2 g (0.1 mole) acetic anhydride was slowly added under stirring. After 2 hours diethyl ether and water were added. The phases were separated and the organic phase was dried, filtered and evaporated in vacuo. The product contained 15% starting material and was therefore redissolved in diethyl ether and washed twice with dilute sodium carbonate. Drying, filtration and evaporation of solvents in vacuo gave 12 g (yield 67%) of 2-(4-methylcarbonyloxyphenyl)-1-ethanol which was used without further purification.
