반응 단계

To one liter of concentrated sulfuric acid was added, at 5° C., 100 ml of 1,2,3,4-tetrafluorobenzene. Then a mixture of 100 ml of 70% nitric acid premixed with 200 ml of concentrated sulfuric acid at 0° C. was slowly added. The reaction was stirred at 0° C. for one hour, and then one hour at 25° C. The mixture was poured over ice and extracted with dichloromethane, which was dried and concentrated to give 120 g of a thick residue which was one spot thin layer chromatography. This product was used for the next step without purification.
