To the solution of N-(3-bromopropyl)phthalimide (30.1 g) in acetone (200 ml) were added 1-isopropyl piperazine (23.0 g) and potassium carbonate (41.4 g). The resulting mixture was refluxed with stirring for 4 hours. The reaction maxture was cooled and then filtered. The filter cake was washed with acetone. The filtrate and washing were combined and evaporated under reduced pressure to give an oil of N-[3-(4-isopropyl-1-piperazinyl)propyl]phthalimide (43.5 g).
