Versuchsvorschrift

To a stirring solution of 5-amino-2-methylbenzoic acid (600 mg, 4.0 mmol) in anhydrous THF (25 mL), 3-(trifluoromethyl)benzoyl chloride (910 mg, 4.3 mmol) was added slowly. The mixture was stirred at room temperature under argon for overnight. The solvent was removed under reduced pressure and re-crystallized from acetone to afford the title compound as a white solid (600 mg, 47%).
