1-(2,3-Dichlorophenyl)piperazine hydrochloride (3.16 g, 11.8 mmol) and potassium carbonate (4.08 g, 29.5 mmol) were added to the solution of 2-(2-bromoethyl)isoindoline-1,3-dione (3 g, 11.8 mmol) in DMF (20 ml). The reaction mixture was stirred for overnight at room temperature. After reaction complete, water (40 ml) was added and then normal work-up was taken. The residue was purified with normal phase preparative column to afford title compound (3.87 g, 81% yield) as white solid.
