In a 25 ml, microwave tube was added sodium hydride (0.6 g) in tetrahydrofuran (10 mL) to give a suspension. 2-(2-Methoxyethoxy)ethanethiol (1 g) was added slowly. After stirring for 30 minutes, 3-chloro-4-fluorobenzenesulfonamide (1.54 g) dissolved in 10 mL tetrahydrofuran was added slowly. The mixture was heated at 110° C. for 30 minutes in a Biotage Initiator microwave reactor. Water was added, the product was extracted with ether (20 mL×3), dried over Na2SO4, filtered, and the solvent was removed under reduced pressure. The crude product was purified by flash chromatography on silica eluting with 0-25% ethyl acetate in hexane.
