Procedure

Into a 250 mL round-bottomed flask was added sodium hydride (0.5 g) in tetrahydrofuran (10 mL) and then 1,4-dioxaspiro[4.5]decan-7-ylmethanol (0.5 g) was added. After the mixture stirred at room temperature for 20 minutes, 4-fluoro-3-nitrobenzenesulfonamide (0.65 g) was added. The mixture was stirred at room temperature for overnight. Water (20 mL) was added slowly. The aqueous layer was extracted by dichloromethane (3×20 mL). The combined organic layers were dried over Na2SO4. After filtration, and concentration of the filtrate, the residue was purified by reverse phase chromatography, eluting with 30-60% acetonitrile in water with 0.1% trifluoroacetic acid.
