Procedure
9.2 A mixture of 5.4 g (11.7 mmol) of tert-butyl (2R,4R)-4-methanesulfonyloxy-2-[4-(3-oxomorpholin-4-yl)phenylcarbamoyl]pyrrolidine-1-carboxylate and 3.69 g (56.8 mmol) of sodium azide in 50 ml of dimethylformamide (DMF) is stirred at 60° C. for 12 hours. The insoluble matter is subsequently filtered off, and the filtrate is evaporated to dryness under reduced pressure. The residue is then dissolved in 20 ml of water, and the aqueous solution is extracted twice with 10 ml of methylene chloride each time. The combined methylene chloride extracts are finally washed once with 10 ml of saturated sodium chloride solution and dried over sodium sulfate. Removal of the drying agent by filtration and stripping-off of the solvent gives 4.8 g (100%) of tert-butyl (2R,4S)-4-azido-2-[4-(3-oxomorpholin-4-yl)phenylcarbamoyl]pyrrolidine-1-carboxylate as slightly yellow crystals, ESI 431.
