Reaction Conditions

Reaction Steps

To 5 ml of N,N-dimethylformamide were dissolved 0.39 g (2.0 mmol) of 6-butoxynicotinic acid, synthesized by a method in accordance with one used in Intermediate Production Example 1, and 0.40 g (2.0 mmol) of 4,4-difluoro-3-methyl-3-butenyl methanesulfonate, followed by the addition of 0.34 g (4.0 mmol) of sodium hydrogencarbonate and stirring at 100° C. for 3 hours. The reaction liquid was then poured in water and extracted with diethyl ether. 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 (diisopropyl ether:hexane=1:7) to obtain 0.45 g (yield: 75%) of 4,4-difluoro-3-methyl-3-butenyl 6-butoxynicotinate.
