(2,3,4-三氟苯基) 乙酸甲酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 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). concentrated under reduced pressure Water and ethyl acetate were added to the residue the organic layers were separated the aqueous layer was extracted with ethyl acetate The combined organic layer was washed with saturated brine dried over anhydrous magnesium sulfate the solvent was evaporated under reduced pressure
