Versuchsvorschrift

piperazine (1.23 g, 14.32 mmol) was treated with 6-chloro-2,4-dimethoxy pyrimidine (0.5 g, 2.86 mmol) in acetonitrile (5 mL) and the reaction mixture was stirred at room temperature for 6 hours. Subsequently the reaction mixture was poured onto ice-cold water (25 ml) and extracted with ethyl acetate (25 ml). The organic layer was washed with aqueous sodium bicarbonate solution and evaporated to furnish the required compound.
