Procedure

3-(1,1-Dimethyl-2-methylsulfanyl-ethylimino)-4-iodo-3H-isobenzofuran-1-one (0.53 g) and 1-(3-methyl-4-aminobenzyl)-3,5-bis(trifluoromethyl)-1H-pyrazole (0.45 g) were dissolved in acetonitrile (15 ml), to which p-toluenesulfonic acid monohydrate (0.01 g) was added and the mixture was stirred at 60° C. for 3 hours. After finishing the reaction, the solvent was distilled off under reduced pressure and the residue was purified by silica gel column chromatography to obtain N1-[4-(3,5-bistrifluoromethylpyrazol-1-ylmethyl)-2-methylphenyl]-N2-(1,1-dimethyl-2-methylsulfanylethyl)-3-iodophthalamide (0.91 g). mp. 83-87° C.
