Reaction Steps

To a solution of (2R,5S)-2-methanesulfonyloxymethyl-5-(3-trifluoromethoxy-phenylcarbamoyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (465 mg, 0.97 mmol) in DMF (3 mL) was added a solution of sodium azide (313 mg, 4.82 mmol) in water (0.5 mL) and the mixture was stirred at 80° C. under nitrogen atmosphere overnight. EtOAc and a saturated aqueous solution of NaHCO3 were added, the layers were separated and the aqueous one back-extracted with EtOAc. The combined organic extracts were washed with brine, dried over Na2SO4, filtered and concentrated. The crude residue was purified by flash column chromatography on silica gel (c-hexane/EtOAc gradient 100:0 to 1:1) to give the desired compound. MS (LC-MS): 330 [MH−Boc]+; tR (HPLC conditions b) 5.75 min.
