실험 절차
Trifluoroacetic acid (4.0 mL) was added to the obtained tert-butyl 4-(2-methoxyphenyl)-2-(5-phenylpyridine-3-carboxamido)benzoate (61 mg), followed by stirring at room temperature for 1 hour. The solvent was evaporated under reduced pressure, and diisopropyl ether was added to the obtained residue. The solid substance was collected by filtration, and dioxane (3.0 mL), water, and a 2 mol/L aqueous solution of sodium hydroxide (0.080 mL) were added to the obtained residue. After adjusting the pH to 7.6 with 1 mol/L hydrochloric acid, the solid substance was collected by filtration to obtain 32 mg of 4-(2-methoxyphenyl)-2-(5-phenylpyridine-3-carboxamido)benzoic acid as a white solid.
