Versuchsvorschrift

To (4S,5R)-3-(4-(4-chlorophenoxy)phenyl)-5-(hydroxymethyl)-4-phenyloxazolidin-2-one (14 mg, 0.035 mmol) in THF (1 mL) was added NaH (˜5 mg) and the reaction was stirred for 10 min. at room temperature. Iodomethane (˜0.01 mL) was added and the reaction was stirred for an additional 2 h. NaHCO3 aqueous solution was added to quench, followed by dilution with water and ethyl acetate. The organic phase was washed with brine, dried (MgSO4), and concentrated. Flash chromatography (0-30% ethyl acetate/hexanes) yielded 8 mg (57%) of the title compound as a colorless oil. 1H NMR (CDCl3) δ (ppm) 7.23-7.32 (m, 7H), 7.16-7.19 (m, 2H), 6.78-6.82 (m, 4H), 5.16 (d, 1H, J=5.7 Hz), 4.36 (dd, 1H, J=9.3, 3.9 Hz), 3.63 (ddd, 2H, J=18.4, 11.0, 4.1), 3.41 (s, 3H). HPLC-MS calculated C23H20ClNO4 (M+H+): 410.1, found: 410.1.
