HCID 6422Trifluoroacetic acidSolvent

Procedure

Trifluoroacetic acid 10 mL was added to the obtained tert-butyl 2-(4-fluoroanilino)-4-(3-(hydroxymethyl)phenyl)benzoate, and it was stirred at room temperature for 1 hour. The solvent was removed under reduced pressure, and the obtained residue was refined by reversed-phase silica gel column chromatography [eluent; 70-100% acetonitrile/0.1% trifluoroacetic acid aqueous solution] to give 2-(4-fluoroanilino)-4-(3-(hydroxymethyl)phenyl)benzoic acid 7.7 mg of a pale yellow solid.
