Reaction Steps
A mixture of (2S,4R)-4-fluoro-2-methanesulfonyloxymethyl-pyrrolidine-1-carboxylic acid tert-butyl ester (3.3 g, 11.1 mmol) and NaN3 (721 mg, 11.1 mmol) in DMF (50 mL) was stirred at 75° C. under nitrogen overnight. The mixture was diluted with water and extracted with EtOAc (×3). The combined organic extracts were washed with water (×3), dried over Na2SO4, and concentrated. The crude residue was purified by flash column chromatography on silica gel (c-hexane/EtOAc 100/0 to 0/100) to give the desired material. 1H-NMR (400 MHz, DMSO): δ (ppm) 5.25 (d, 1H), 4.03 (m, 1H), 3.92-3.70 (m, 2H), 3.5-3.25 (m, 2H), 2.27 (m, 1H), 2.2-1.8 (m, 1H), 1.43 (s, 9H).
