Methyl 4-bromo-2-sulfo-butyrate (1.07 g, 4.11 mmol) and sodium azide (0.70 g (10.7 mmol) in DMF (50 ml) was stirred overnight. The mixture was evaporated and purified by SiO2 chromatography and eluted with 1:5:0.01 CH3OH/CH2Cl2/HAc and crystallized with CH3OH/Toluene/Hexane to afford 1.00 g (95%) of the title compound. m.p=267-272° C. (decomp). 1H NMR (DMF-d7): 12.06 (br, 1H), 3.65 (s, 3H), 3.59 (dd, 1H, J=5.4, 8.9 Hz), 3.47 (m, 2H), 2.24 (m, 2H). 13C NMR 171.10, 64.29, 52.24, 50.64, 21.35. ESI MS m/z+267.9 (M+2Na—H), m/z−222.0 (M−H). HRMS m/z−(C5H9N3O5S—H) calcd 222.0185. found 222.0179.
