Procedure
Trifluoroacetic acid 5.0 mL was added to the obtained tert-butyl 2-((benzothiophen-5-yl)amino)-4-(3-(tert-butoxycarbonyloxy)phenyl)benzoate, and it was stirred at room temperature for 3 hours. The solvent was removed under reduced pressure,diisopropyl ether was added to the obtained residue, and solid matter was filtrated to give 2-((benzothiophen-5-yl)amino)-4-(3-hydroxyphenyl)benzoic acid 30 mg of a yellow solid.
