Procedure
Trifluoroacetic acid 10 mL was added to the obtained tert-butyl 2-(4-fluoroanilino)-4-(2-methoxypyridin-5-yl)benzoate, and it was stirred at room temperature for 1 hour. The solvent was removed under reduced pressure, the obtained residue was refined by reversed-phase silica gel column chromatography [eluent; 55-90% acetonitrile/0.1% trifluoroacetic acid aqueous solution] to give 2-(4-fluoroanilino)-4-(2-methoxypyridin-5-yl)benzoic acid trifluoroacetate.
