Versuchsvorschrift

To a solution of 4,6-dichloro-2-methylpyrimidine (3.00 g) in dichloromethane (35 mL) was added 2-(piperazin-1-yl)ethanol (4.51 mL) at room temperature, and the mixture was stirred for 4 hr. To the reaction mixture was added triethylamine (0.513 mL) at room temperature, and the reaction mixture was stirred overnight. The resulting solid was collected by filtration, washed with dichloromethane, and dried under reduced pressure to give the title compound (4.08 g).
