Procedure
A 1 mol/L aqueous solution of sodium hydroxide (0.13 mL) was added to an ethanol (4.0 mL) suspension of the obtained 2-(5-phenylpyridine-3-carboxamido)-4-(thiophen-2-yl)benzoic acid (54 mg) at room temperature, followed by stirring at the same temperature for 2 hours and 30 minutes. The solvent was evaporated under reduced pressure, and water was added to the obtained residue. The solid substance was collected by filtration to obtain 35 mg of sodium 2-(5-phenylpyridine-3-carboxamido)-4-(thiophen-2-yl)benzoate as a white solid.
