A solution of N-(4-chloromethylphenylmethyl) acetamide (0.93 g), 1-(4,6-dimethoxypyrimidin-2-yl)piperazine (0.94 g) and potassium carbonate (0.97 g) in dimethylformamide (10 ml) was stirred at 80° C. for 1.5 hr. The reaction mixture was poured into water and extracted with ethyl acetate. The extract was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated to give a brown oil (2.0 g). The obtained brown oil was crystallized from ethyl acetate:diisopropyl ether(1:3, 40 ml) to give the title compound (1.3 g) as pale-yellow crystals, m.p.=130-131° C.
