Trichloroacetic Acid → 2-(2,3-Dimethoxyphenyl)acetaldehyde

Participants

Reaction Steps

Trichloroacetic acid (817 mg, 5.00 mmol) was added to a solution (10 mL) of 2-(2,3-dimethoxyphenyl)ethenyl methyl ether (808 mg, 4.16 mmol) in dichloromethane at room temperature and stirred for 2 hours. The reaction mixture was diluted with water and extracted twice with ethyl acetate. The extract solution was dried over anhydrous sodium sulfate and then concentrated under reduced pressure to obtain 2-(2,3-dimethoxyphenyl)acetaldehyde (780 mg, 100%) as a yellow oil.
