Reaction Steps
A mixture of 4,6-dichioropyrimidine (29.5 g), N-benzylpiperazine (44.0 g) and DIPEA (44 ml) was suspended in p-xylene (400 ml) and heated at 138° C. under reflux. After 18 hours the reaction mixture was allowed to cool to room temperature and filtered. The filtrate was evaporated using high vacuum pump apparatus to obtain 1-(benzyl)-4-(4-chloropyrimidin-6-yl)piperazine a brown solid, 60.5 g (105% based on 4,6-dichloropyrimidine);
