To a mixture of 2-(but-3-en-1-yl)isoindoline-1,3-dione obtained in step 1 (0.65 g, 3.22 mmol) in dichloromethane (10 ml), was added m-chloroperoxybenzoic acid (1.11 g, 6.44 mmol) at 0° C. The resulting reaction mixture was stirred at room temperature for 10 hours. After the reaction complete, the reaction mixture thus obtained was filtered through a plug of Celite. The filtrate was washed with 1 N sodium hydroxide solution and brine. The organic phase thus separated was dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure to obtain the title compound (0.65 g). The compound was used for the next step without further purification.
