Procedure

In a 100 mL round-bottomed flask 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 the mixture stirred for 30 minutes, 4-fluoro-3-nitrobenzenesulfonamide (1.616 g) in 10 ml tetrahydrofuran was added slowly. After the mixture stirred overnight, water was added slowly, and ethyl acetate (20 ml×3) was used to extract the product. The combined organic layers were dried over Na2SO4. After the mixture was filtered and concentrated, the crude product was added to a silica gel column and purified eluting with 0-10% methanol in dichloromethane.
