Trifluoroacetic acid → 3,4-Dichloro-2-fluorophenol

Participants

Reaction Steps

Trifluoroacetic acid (0.5 mL) was added to a solution of 3-chloro-2-fluorophenol (750 mg, 5.12 mmol) and N-chlorosuccinimide (684 mg, 5.12 mmol) in acetonitrile (30 mL) and the reaction mixture stirred for 24 h. The mixture was concentrated in vacuo and purified by chromatography on silica gel with heptane:EtOAc (9:1, v/v) as eluent to afford the title compound (440 mg, 48%) as a pale yellow solid.
