Procedure

To bromomaleimide (300 mg, 1.69 mmol) and sodium acetate (138 mg, 1.69 mmol) in methanol (100 mL) was added hexanethiol (237 μL, 1.69 mmol). After 5 minutes solvent removed in vacuo and purification by flash chromatography (10% ethyl acetate in petroleum ether) afforded hexylsulfanylmaleimide as a cream powder (362 mg, 1.69 mmol) in 100% yield.
