Trifluoroacetic acid → HCID 57667802, compound

Participants

Reaction Steps

Trifluoroacetic acid 5.0 mL was added to the obtained tert-butyl 2-((benzo-1,3-dioxol-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, and the obtained residue was refined by reversed-phase silica gel column chromatography [eluent; 50-90% acetonitrile/0.1% trifluoroacetic acid aqueous solution] to give 2-((benzo-1,3-dioxol-5-yl)amino)-4-(3-hydroxyphenyl)benzoic acid 17 mg of a yellow solid.
