In analogy to the procedure described in example 20 a], 5-chloromethyl-1-methyl-3-(4-trifluoromethyl-phenyl)-1H-pyrazole (example 9 a]) was treated with sodium iodide in acetone to obtain 5-iodomethyl-1-methyl-3-(4-trifluoromethyl-phenyl)-1H-pyrazole as yellow solid which was used in the next step without further purification.
