Procedure

5-chloromethyl-1-ethyl-3-(4-trifluoromethyl-phenyl)-1H-pyrazole was prepared in analogy to the prepaparation of 5-chloromethyl-1-ethyl-3-(3,4,5-trimethoxy-phenyl)-1H-pyrazole described by Kodama et al. (U.S. Pat. No. 6,472,386), but starting from 4-trifluoromethylacetophenone instead of 3′4′5′-trimethoxyacetophenone and using ethyl hydrazine instead of methylhydrazine.
