Thio phenol (100 mg, 0.85 mmol), 2-chloro-1-(4-(naphthalen-2-ylsulfonyl)piperazin-1-yl)ethanone (compound 5, 0.3 g, 0.85 mmol) and anhydrous potassium carbonate (0.293 g, 2.125 mmol) were stirred for over night in dry acetonitrile (20 mL). The mixture was then stirred into a large volume of water and the solution extracted with ether. Unreacted phenol was removed with cold 1N NaOH solution. The ether extract was dried over anhydrous sodium sulphate, filtered and concentrated under reduced pressure. The crude material was purified by column chromatography to yield the title compound in quantitative yield.
