Reaction Conditions

Reaction Steps

10 g of 2,5-difluorophenol was dissolved in 120 ml of dimethylformamide, and 21 g of potassium carbonate and 8.57 ml of allyl bromide were added to the resulting solution in this order at room temperature. The resulting mixture was stirred at 80° C. for one hour, followed by the addition of water. The resulting mixture was extracted with ethyl acetate, and the organic layer was washed with brine, dried over anhydrous magnesium sulfate, and evaporated. The resulting residue was subjected to silica gel chromatography (developer: 5% ethyl acetate/n-hexane) to give 13 g of the title compound as a colorless oil.
