Procedure

100 g (4.20 mmoles) of 3-trifluoroacetylamino-1-methyl-4-nitropyrazol are heated with 2.12 g (16.8 mmoles) methyl iodide in 10 ml absolute acetone to 50° C. 940 mg (16.8 mmoles) powdered potassium hydroxide are then added and the reaction mixture is heated to boiling for 5 minutes. The solvent is distilled off in the rotary evaporator in vacuum and the residue is separated by means of column chromatography using silica gel with ether/toluene (5:1).
