Procedure

N-[2-Ethyl-4-(1,1,1,2,3,3,3-heptafluoropropan-2-yl)-6-methylphenyl]-4-fluoro-3-nitrobenzamide (1.5 g, see WO 2005/073165) and 1H-1,2,4-triazole (0.24 g) were dissolved in N,N-dimethylformamide (15 ml). To the solution, potassium carbonate (0.88 g) was added and the mixture was stirred under heating at 70° C. for 3 hours. After cooling to room temperature, the reaction solution was diluted with water and extracted twice with ethyl acetate. The organic phases were combined, washed with water and dried over magnesium sulfate. After filtering off the drying agent, the solvent was distilled off under reduced pressure to obtain a crude product. The resulting crude product was purified by column chromatography to obtain N-[2ethyl-4-(1,1,1,2,3,3,3-heptafluoropropan-2-yl)-6-methylphenyl]-3-nitro-4-(1H-1,2,4-triazol-1-yl)benzamide (1.4 g, yield 80%).
