Reaction Steps
1-Benzyl-piperazine (5.86 g, 33.3 mmol), 2-amino-4,6-dichloro-pyrimidine (5.46 g, 33.3 mmol) and Cs2CO3 (10.8 g, 36.6 mmol) were combined in anhydrous N,N-dimethylformamide (DMF) (50 mL) and stirred at 90° C. in dry atmosphere for 5 h. The DMF was removed in vacuo, the residue was dissolved in acetone, and 4-(4-Benzyl-piperazin-1-yl)-6-chloro-pyrimidin-2-ylamine (8.5 g, 86%) was is crystallized form acetone.
