Versuchsvorschrift
To acetic anhydride (20 ml) was added 70% nitric acid (2 ml) dropwise in an ice-bath. During the addition, the internal temperature of the mixture temporarily rose to 25° C. and dropped to 0° C. To the mixture was added 1-(4-methoxyphenyl)-5-[4-(methylsulfonyl)phenyl]-3-(trifluoromethyl)pyrazole (2.0 g) portionwise. The reaction mixture was allowed to stir for 5 hours and poured into ice-water. The precipitate formed was collected by filtration and dried to give 1-(4-methoxy-3-nitrophenyl)-5-[4-(methylsulfonyl)phenyl]-3-(trifluoromethyl)pyrazole (2.15 g).
