실험 절차
76.6 g of 3-cyano-2,4,5-trifluoro-benzoyl fluoride were initially introduced together with 1 g of anhydrous aluminium chloride at 60-65° C., and 25 g of silicon tetrachloride were then added dropwise at the rate of gas evolution. After the evolution of gas at 65° C. had ceased, the mixture was distilled under reduced pressure. In the boiling range from 120-122° C./14 mbar, 73.2 g of 3-cyano-2,4,5-trifluoro-benzoyl chloride passed over.
