Versuchsvorschrift

To a mixture of 2-(2-(oxiran-2-yl)ethyl)isoindoline-1,3-dione obtained in step 2 (0.30 g, 1.38 mmol) and potassium carbonate (0.48 g, 3.45 mmol) in N,N-dimethylformamide (3.0 ml), was added 1-(2,3-dimethylphenyl)piperazine hydrochloride (0.31 g, 1.38 mmol) at room temperature. The resulting reaction mixture was stirred at 110° C. for 18 hours. After the reaction complete, the reaction mixture thus obtained was filtered through a plug of Celite. The filtrate was concentrated under reduced pressure to obtain the title compound (0.26 g). The compound was used for the next step without further purification.
