Trifluoroacetic acid 10 mL was added to the obtained tert-butyl 2-((benzothiophen-5-yl)amino)-4-(indolin-1-yl)benzoate, and it was stirred at room temperature for 2 hours. The solvent was removed under reduced pressure, methanol was added to the obtained residue, and solid matter was filtrated to give 2-((benzothiophen-5-yl)amino)-4-(indolin-1-yl)benzoic acid 67 mg of a brown solid.
