Procedure

A solution of N-(4-chloromethylphenylmethyl)acetamide (1.6 g), 1-(pyrazin-2-yl)piperazine (1.3 g) and potassium carbonate (1.6 g) in dimethylformamide (20 ml) was stirred at 70-80° C. for 7 hr. The reaction mixture was poured into water and extracted with chloroform. The extract was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated and the obtained residue was purified by silica gel column chromatography (developing solvent; chloroform:methanol=20:1) to give a pale-yellow solid (1.8 g). The obtained pale-yellow solid was crystallized from hexane-ethyl acetate to give the title compound (1.2 g) as pale-yellow crystals, m.p.=118-119° C.
