Potassium Carbonate → HCID 12800894, compound

Participants

Reaction Steps

Potassium carbonate (5.8 g) was added to a solution of 5-chloro-2-methylsulphonylpyrimidine (6.7 g) and 4-methoxythiophenol (5.0 g) in methyl ethyl ketone (50 ml) and the mixture was stirred and boiled under reflux for 3 hours. The solvent was evaporated under reduced pressure and the residue partitioned between chloroform and 5% sodium hydroxide aqueous solution. The chloroform extracts were dried (Mg SO4) and evaporated under reduced pressure to give 5-chloro-2-(4-methoxyphenylthio)pyrimidine (8.5 g) as a colourless solid, m.p. 75° C.
