Procedure
To a stirring solution of 5-amino-2-chlorobenzoic acid (1.74 g, 10.1 mmol) in anhydrous THF (60 mL), 3-(trifluoromethyl)benzoyl chloride (2.33 g, 11.2 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/chloroform (v/v 1:1) to afford the title compound as a white solid (1.5 g, 43%).
