실험 절차
To 3 ml of N,N-dimethylformamide were dissolved 0.50 g (1.6 mmol) of 4,4-difluoro-3-methyl-3-butenyl 2-methanesulfonyl-4-methylpyrimidine-5-carboxylate, followed by the addition of 0.28 g (3.2 mmol) of N-butyl-N-methylamine and stirring at room temperature for 30 minutes. 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 (ethyl acetate ether:hexane=1:7) to obtain 0.41 g (yield: 80%) of 4,4-difluoro-3-methyl-3-butenyl 2-(N-butyl-N-methylamino)-4-methylpyrimidine-5-carboxylate.
