Procedure

Trifluoroacetic acid 10 mL solution of tert-butyl 4-((E)-2-(3,4-dimethylphenyl)vinyl)-2-(4-fluoroanilino)benzoate was stirred at room temperature for 2 hours. The solvent was removed under reduced pressure, and the obtained residue was refined by reversed-phase silica gel column chromatography [eluent; 85-100% acetonitrile/0.1% trifluoroacetic acid aqueous solution] to give 4-((E)-2-(3,4-dimethylphenyl)vinyl)-2-(4-fluoroanilino)benzoic acid.
