Reaction Steps

A suspension of 2-chloro-4-methoxypyrimidine (21.5 g) and piperazine (64.0 g) in acetonitrile (200 ml) was refluxed for 30 min. The reaction mixture was poured into water (500 ml) and extracted with chloroform (400 ml). The extract was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated to give the title compound (26.0 g) as a pale-yellow oil.
