Procedure

4-Chlorothiophenol (2.89 g, 20 mmol), N-(6-bromohexyl)-phthalimide (6.20 g, 20 mmol) and K2CO3 (5.53 g, 40 mmol) were suspended in DMF (50 mL) under an atmosphere of argon and stirred at 90° C. for 23 h. The solvent was evaporated under reduced pressure and the residue was partitioned between water (100 mL) and CH2Cl2 (150 mL). The aqueous layer was extracted with CH2Cl2 (2×100 mL), the combined org. layers were dried over Na2SO4, filtered and the solvent was removed under reduced pressure to give the title compound, pure enough for further reactions.
