Versuchsvorschrift

Acetyl-{3-[4-(1,1-dioxo-hexahydro-1λ6-thiopyran-4-yl)-3-fluoro-phenyl]-2-oxo-oxazolidin-5(R)-ylmethyl}-carbamic acid 1-chloro-ethyl ester (11) (0.20 g, 0.41 mmol) and sodium iodide (0.061 g, 0.41 mmol) are placed in acetonitrile (25 mL) and stirred at RT overnight. Cesium propionate (0.17 g, 0.82 mmol) is then added and the reaction is heated at reflux overnight. After cooling to RT, water is added and the reaction mixture is extracted with EtOAc and then with dichloromethane. The organic phases are washed separately with brine and then the organic layers are combined, dried over MgSO4, filtered, and conc in vacuo. The isolated residue is subjected to silica gel flash chromatography, eluting with MeOH/CH2Cl2 gradient (0-5% MeOH over 1 hour and 20 minutes) to afford the title compound. Isolated yield: 67%. 1H NMR (400 MHz, CDCl3): δ 7.48-7.42 (m, 1H), 7.21-7.17 (m, 1H), 7.13-7.10 (m, 1H), 6.90-6.85 (m, 1H), 4.83-4.69 (m, 1H), 4.14-3.98 (m, 3H), 3.73-3.64 (m, 1H), 3.13-3.04 (m, 5H), 2.52 (d, 3H), 2.48-2.31 (m, 3H), 2.29-2.13 (m, 2H), 1.56-1.51 (m, 4H), 1.15-1.07 (m, 3H).
