Versuchsvorschrift

To a solution of (S)-tert-butyl 3-(hydroxymethyl)pyrrolidine-1-carboxylate (0.300 g) in tetrahydrofuran (5 mL) was added sodium hydride (0.238 g). After stirring for 15 minutes, 4-fluoro-3-nitrobenzenesulfonamide (0.295 g) was added and reaction stirred at room temperature. After 1 hour, the reaction was partitioned between water (25 mL) and dichloromethane (50 mL) and the reaction quenched with 1N aqueous HCl (5.96 mL). The organic layer was separated, dried over magnesium sulfate, filtered, and concentrated. Silica gel chromatography (Reveleris 12 g) eluting with a gradient of 0.2% to 2% methanol/dichloromethane over 30 minutes (flow=36 m/minute) gave the title compound.
