Trifluoroacetic acid (5 mL) was added to the obtained tert-butyl 4-phenyl-2-(6-phenylpyridine-3-carboxamido)benzoate, followed by stirring at room temperature for 3 hours. The solvent was evaporated under reduced pressure, and methanol was added to the obtained residue. The solid substance was collected by filtration to obtain 53 mg of 4-phenyl-2-(6-phenylpyridine-3-carboxamido)benzoic acid as a light yellow solid.
