Procedure
By the method of Example 5, Step B, 137.4 g (0.374 mole) of 4-ethoxycarbonyl-5-methyl-1-(2,6-dichloro-4-trifluoromethylphenyl)-1H-pyrazole dissolved in 767 mL of ethanol was reacted with 23.6 g (0.59 mole) of sodium hydroxide dissolved in 413 mL of water. After being neutralized with 180 mL of 10% hydrochloric acid, this reaction yielded 119 g of 4-carboxy-5-methyl-1-(2,6-dichloro-4-trifluoromethylphenyl)-1H-pyrazole. The nmr spectrum of this solid was consistent with the proposed structure.
