Procedure

To a DCM 200 mL solution of 2,4,6-trifluorobenzoic acid (20 g, 0.11 mol) and DMF (0.5 mL, 6.46 mmol) was added oxalyl chloride (21.6 g, 0.17 mol) dropwise. The reaction mixture was stirred at room temperature for 1 hr and the solvent was removed under reduced pressure to give the title compound as crude product (22 g).
