실험 절차

By the method of Example 5, Step H, 1.5 g (0.0045 mole) of 4-cyano-5-formyl-1-(2,6-dichloro-4-trifluoromethylphenyl)-1H-pyrazole and 1.0 g (0.0096 mole) of malonic acid were reacted in the presence of 5 mL of pyridine and 10 drops of piperidine, yielding 0.96 g of 3-[4-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-1H-pyrazol-5-yl]acrylic acid. The nmr spectrum of this solid was consistent with the proposed structure.
