Procedure
Trifluoroacetic acid 5.0 mL was added to tert-butyl 2-((4-(dimethylamino)phenyl)amino)-4-phenethylbenzoate, and it was stirred at room temperature for 3 hours. The solvent was removed under reduced pressure, ethyl acetate and water were added to the obtained residue, and it was adjusted to pH6.5 with saturated sodium hydrogen carbonate aqueous solution. The organic layer was separated and collected,dried over anhydrous magnesium sulfate after washing with saturated sodium chloride aqueous solution, and the solvent was removed under reduced pressure. Diisopropyl ether was added to the obtained residue, solid matter was filtrated to give 2-((4-(dimethylamino)phenyl)amino)-4-phenethylbenzoic acid 83 mg of a pale yellow solid.
