Reaction Conditions

Reaction Steps

To 50 ml of N,N-dimethylformamide were dissolved 6.6 g (33 mmol) of 4,4-difluoro-3-methyl-3-butenyl methanesulfonate and 7.6 g (36 mmol) of 2-butoxy-4-methylpyrimidine-5-carboxylic acid, followed by the addition of 3.6 g (43 mmol) of sodium hydrogencarbonate and stirring at 100° C. for 2 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=1:9) to obtain 3.3 g (yield: 32%) of 4,4-difluoro-3-methyl-3-butenyl 2-butoxy-4-methylpyrimidine-5-carboxylate.
