Reaktionsschritte

(Tetrahydro-2H-pyran-4-yl)methanol (2.0 g) in tetrahydrofuran (20 mL) was treated with 60% NaH (1.377 g). The solution was stirred for 20 minutes at the room temperature. To this solution was added 4-fluoro-3-nitrobenzenesulfonamide (2.84 g) portion-wise. The reaction was stirred for another 2 hours. The mixture was poured into water, neutralized with 10% HCl, and extracted with ethyl acetate three times. The combined organic layers were washed with brine, dried over MgSO4, filtered, and concentrated. The residue was purified with flash column chromatography on silica gel eluting with 20-60% ethyl acetate in hexanes.
