Thiophenol → HCID 23020229, compound

Participants

Reaction Steps

To 5 ml of tetrahydrofuran were dissolved 0.56 g (1.8 mmol) of 4,4-difluoro-3-methyl-3-butenyl 2-methanesulfonyl-4-methylpyrimidine-5-carboxylate and 0.21 g (1.9 mmol) of thiophenol, followed by the addition of 0.30 g (2.8 mmol) of sodium carbonate and stirring at room temperature for 1 hour. 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=1:8) to obtain 0.54 g (yield: 88%) of 4,4-difluoro-3-methyl-3-butenyl 4-methyl-2-(phenylthio)pyrimidine-5-carboxylate.
