실험 절차
A solution of 2-{3,5-difluoro-4-[2-methoxyvinyl]phenyl}propan-2-ol (5.0 g, 22 mmol) in acetone (25 mL) was added dropwise to 4 M aqueous hydrochloric acid (25 mL, 100 mmol) with ice-water cooling, keeping the temperature below 10° C. Then the mixture was stirred at room temperature for six hours. The resulting mixture was extracted with ethyl acetate (2×) and the combined organic phases were washed with saturated aqueous sodium bicarbonate and brine. The organic layer was then dried and concentrated in vacuo to afford the title compound.
