Reaction Steps

To 7 ml of N,N-dimethylformamide were dissolved 0.50 g (2.5 mmol) of 4,4-difluoro-3-methyl-3-butenyl methanesulfonate and 0.56 g (2.5 mmol) of 2-cyclohexyl-4-methylthiazole-5-carboxylic acid, followed by the addition of 0.42 g (5.0 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 (ethyl acetate:hexane=1:9) to obtain 0.64 g (yield: 78%) of 4,4-difluoro-3-methyl-3-butenyl 2-cyclohexyl-4-methylthiazole-5-carboxylate.
