実験手順
To 10 ml of N,N-dimethylformamide were dissolved 0.50 g (2.2 mmol) of 6,6-difluoro-5-methyl-5-hexenyl methanesulfonate and 0.45 g (2.4 mmol) of 4-chloro-5-ethyl-2-methyl-2H-pyrazole-3-carboxylic acid, followed by the addition of 0.37 g (4.4 mmol) of sodium hydrogencarbonate and stirring at 100° C. for 7 hours. The reaction liquid was then poured in water and extracted with ethyl acetate. The organic layer was washed with water and a saturated saline solution in this order, followed by drying over anhydrous magnesium sulfate and concentration under reduced pressure. The residue was purified with silica gel column chromatography (ethyl acetate:hexane=1:19) to obtain 0.52 g (yield: 74%) of 6,6-difluoro-5-methyl-5-hexenyl 4-chloro-5-ethyl-2-methyl-2H-pyrazole-3-carboxylate.
