Procedure

By the method of Example 5, Step D, 106 g (0.331 mole) of 4-cyano-5-methyl-1-(2,6-dichloro-4-trifluoromethylphenyl)-1H-pyrazole was reacted with 71.1 g (0.40 mole) of N-bromosuccinimide in 2000 mL of carbon tetrachloride, yielding 136.7 g of 5-bromomethyl-4-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-1H-pyrazole as red oil, a portion of which later solidified.
