Versuchsvorschrift
16.7 g (0.086 mol, 98% pure) of 3-difluoromethyl-1-methyl-1H-pyrazole-4-carbonyl chloride were dissolved at 25° C. in 48.0 g of toluene. The solution was evacuated to 400 mbar and heated to 85° C. Subsequently, within 45 min, 15.0 g (0.087 mol) of 2-bicyclopropyl-2-ylphenylamine, dissolved in 51.6 g of toluene, were metered in and the reaction mixture was stirred for another 1 h. After venting and cooling to 25° C., the mixture was stirred overnight. Subsequently, the mixture was concentrated under reduced pressure and dried. The yield was 27.3 g (96%).
