참여 물질

반응 단계

To a mixture of 2,3,4-trifluorophenol (5.2 g) and acetic anhydride (3.98 mL) in THF (50 mL) was added triethylamine (5.87 mL) at room temperature, and the mixture was stirred for 1 hr and concentrated under reduced pressure. Water and ethyl acetate were added to the residue, the organic layers were separated, and the aqueous layer was extracted with ethyl acetate. The combined organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to give the title compound (6.70 g).
