실험 절차

111 g of 3-cyano-2,4,5-trifluoro-benzoic acid and 84 g of oxalyl chloride are stirred at room temperature for 5 hours in 930 ml of dry methylene chloride with addition of a few drops of dimethylformamide. The methylene chloride is then stripped off and the residue is distilled in vacuo. 117.6 g of 3-cyano-2,4,5-trifluoro-benzoyl chloride are obtained as a yellow oil.
