Sulfuric Acid → Methyl 2-[3,5-bis(trifluoromethyl)phenyl]acetate

Participants

Reaction Conditions

Reaction Steps

To a solution of [3,5-bis(trifluoromethyl)phenyl]acetic acid (10 g) in methanol (50 mL) was added concentrated sulfuric acid (0.5 mL), and the mixture was stirred at 80° C. for 14 hr. The reaction mixture was cooled, basified with saturated aqueous sodium hydrogen carbonate solution, and concentrated under reduced pressure. The residue was diluted with ethyl acetate, and washed with saturated brine. The aqueous layer was extracted again with ethyl acetate, and the combined extract was dried, and concentrated to give methyl [3,5-bis(trifluoromethyl)phenyl]acetate (10.8 g, 100%) as a colorless oil.
