Participants

Reaction Steps

Trifluoroacetic acid 5.0 mL was added to the obtained tert-butyl 2-((4-(dimethylamino)phenyl)amino)-4-phenylbenzoate, 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. Ethyl acetate was added to the obtained residue, and solid matter was filtrated to give 2-((4-(dimethylamino)phenyl)amino)-4-phenylbenzoic acid 61 mg of a yellow solid.
