Versuchsvorschrift

To a mixture of N-(3-bromopropyl)phthalimide (500 mg) in DMSO (8 mL) was added sodium thiomethoxide (144 mg) and the reaction stirred at room temperature for 16 h. Then with water (2 mL) was added and the mixture stirred at room temperature for 10 min. The reaction was diluted with water (20 mL) and extracted into ethyl acetate (2×20 mL). The combined organics were washed with aqueous brine solution (2×20 mL), dried (MgSO4) and reduced in vacuo to give 2-(3-methylsulfanyl-propyl)-isoindole-1,3-dione as a white solid.
