実験手順

To a solution of (4S,5S)-3-(4-(4-chlorophenoxy)phenyl)-5-(aminomethyl)-4-phenyl-oxazolidin-2-one (14 mg, 0.035 mmol) and triethylamine (0.01 mL, 0.07 mmol) in dichloromethane (0.4 mL) at 0° C. was added mesyl chloride (0.005 mL, 0.05 mmol). The reaction mixture was stirred for 10 min and was then quenched with saturated NaHCO3 aqueous solution. Water and dichloromethane was added and the organic was washed with brine, dried (MgSO4), and concentrated. Purification by prep-LC (10-90% Acetonitrile/water (0.05% ammonium acetate) gave 5 mg (31%). 1H NMR (acetone-d6) δ (ppm) 7.45-7.51 (m, 4H), 7.32-7.42 (m, 5H), 6.94-6.97 (m, 4H), 6.66 (t, 1H, J=6.6 Hz), 5.56 (d, 1H, J=5.6 Hz), 4.51, (dd, 1H, J=10.1, 4.7 Hz), 3.59-3.72 (m, 2H), 3.04 (s, 3H). HPLC-MS calculated C23H21ClN2O5S (M+H+): 473.1, found: 473.1.
