Procedure
To a solution of 13.69 g of [2-(methylthio)pyrimidin-4-yl]methanol obtained in stage a) in 250 mL of dichloromethane are added dropwise 7.67 mL of thionyl chloride, followed by 3.91 mL of N,N-dimethylformamide. The reaction mixture is stirred at room temperature for 15 hours and concentrated under reduced pressure. The residue is taken up in diisopropyl ether and the solid formed is filtered off and dried to give 10.28 g of 4-(chloromethyl)-2-(methylthio)pyrimidine, the characteristics of which are as follows:
