Trifluoroacetic acid 10 mL was added to the obtained tert-butyl 2-anilino-4-(2-(3-methoxyphenyl)ethyl)benzoate, and it was stirred at room temperature for 2 hours. The solvent was removed under reduced pressure, and the obtained residue was refined in reversed-phase silica gel column chromatography [eluent; 65-100% acetonitrile/0.1% trifluoroacetic acid aqueous solution] to give 2-anilino-4-(2-(3-methoxyphenyl)ethyl)benzoic acid 4.2 mg of a white solid.
