Procedure

30.7 g (487 mmol) of concentrated nitric acid were added dropwise at 0-5° C. to a solution of 100 g (487 mmol) of N-(4-chloro-2,6-difluorophenyl)acetamide in 500 ml of concentrated sulfuric acid. After the reaction mixture had been stirred for one hour at 0-5° C., it was stirred into ice-water. The resulting solid was separated off, washed twice with water and dried. Yield: 81.3 g (72%);
