Reaction Steps

10 mL of trifluoroacetic acid was added to the obtained tert-butyl 2-(2,3-dimethylbenzamido)-4-(4-(tert-butoxycarbonyl)oxyphenyl)benzoate and stirred ah room temperature for 2 hours. The solvent was evaporated under reduced pressure and ethyl acetate was added to the obtained residue and a solid substance was separated by filtration to obtain 20 mg of 2-(2,3-dimethylbenzamido)-4-(4-hydroxyphenyl)benzoic acid as white solid.
