Versuchsvorschrift
Trifluoroacetic acid (4.0 mL) was added to the obtained tert-butyl 2-(5-phenylpyridine-3-carboxamido)-4-(thiophen-2-yl)benzoate, followed by stirring at room temperature for 2 hours. The solvent was evaporated under reduced pressure, and diisopropyl ether was added to the obtained residue. The solid substance was collected by filtration to obtain 54 mg of 2-(5-phenylpyridine-3-carboxamido)-4-(thiophen-2-yl)benzoic acid as a white solid.
