Reaction Steps

A mixture of 4-chlorobutyronitrile (3.3 g; 0.032 mol), 1-(2-pyrimidinyl)piperazine (3.3 g; 0.032 mol), sodium carbonate (6.4 g; 0.0608 mol) and n-butanol (50 ml) was heated under reflux for 19 hours. After completion of the reaction, the resultant mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with a saturated sodium chloride solution and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure, and the residue was purified by silica gel chromatography to give 1-(3-cyanopropyl)-4-(2-pyrimidinyl)-piperazine. M.P., 56°-57° C.
