Reaction Steps

To 7 ml of N,N-dimethylformamide were dissolved 0.92 g (4.0 mmol) of 6,6-difluoro-5-methyl-5-hexenyl methanesulfonate and 0.72 g (5.2 mmol) of 6-aminonicotinic acid, followed by the addition of 1.30 g (16 mmol) of sodium hydrogencarbonate and stirring at 100° C. for 3 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=1:1) to obtain 0.85 g (yield: 78%) of 6,6-difluoro-5-methyl-5-hexenyl 6-aminonicotinate.
