Reaction Steps
(3R,4R)-1-Benzyl-3-hydroxy-4-methanesulfonyloxymethylpyrrolidine (835 mg), sodium azide (381 mg), and N,N-dimethylformamide (12 mL) were mixed with one another and the mixture was stirred at 120° C. for 1 hour. Subsequently, the reaction mixture was concentrated under reduced pressure. To the resulting residue, water (10 mL) was added and the mixture was extracted with diethyl ether (2×30 mL). The diethyl ether extracts were combined and the combined extract was dried over anhydrous sodium sulfate and was concentrated under reduced pressure. The resulting residue was purified on a silica gel column (eluant=ethyl acetate: methanol=20:1) to give 576 mg of (3R,4R)-3-azidomethyl-1-benzyl-4-hydroxypyrrolidine as a pale brown oil.
