2-[6-(4-Chloro-phenylsulfanyl)-hexylphthalimide (7.47 g, 20 mmol) and hydrazine hydrate (6.1 ml, 100 mmol) were dissolved in THF (50 mL) and EtOH (50 mL) and stirred under reflux for 17 h. The solvent was removed under reduced pressure, the residue was suspended in THF (100 mL) and the precipitate was filtered off, washed with THF (1×50 mL) and the filtrate was concentrated under reduced pressure. The residue was resuspended in THF (25 mL), the precipitate was filtered off and the filtrate was concentrated to give the title compound.
