実験手順
To a stirred suspension of the 4-{4-[(5S)-5-(aminomethyl)-2-oxo-1,3-oxazolidin-3-yl]-2-fluorophenyl}tetrahydro-1λ6-thiopyran-1,1(2H)-dione (4.68 g, 13.74 mmol) prepared according to the PCT international publication WO 97/09328 in CH2Cl2 (100 mL) cooled to 0° C. is added diisopropylethylamine (4.8 ml, 27.48 mmol) followed by a solution of 2.4 g (1.5 7 mmol) of the acid chloride (from Step 4) in CH2Cl2 (10 mL) with a 2 mL rinse. The reaction mixture is stirred at 0° C. fro 30 min then at RT for 3 h. The reaction mixture is partitioned between CH2Cl2 (300 mL) and H2O (200 mL). The phases are separated. The organics are washed with 1N HCl (100 mL), brine (100 mL), dried (MgSO4), filtered and concentrated. The residue is dissolved in CH2Cl2, absorbed onto silca gel and purified on a Biotage 40M with a SIM using 2% CH3OH in CH2Cl2 as the eluent to afford 5.32 g (11.6 mmol, 85%) of the desired carbamate as a white foam. 1H NMR (DMSO) δ 7.96 (t, J=6 Hz, 1H), 7.48 (dd, J=14, 2 Hz, 1H), 7.38 (t, J=9 Hz, 1H), 7.24 (dd, J=9, 2 Hz, 1H), 5.61(s, 2H), 4.74 (m, 1H), 4.12 (t, J=9 Hz, 1H), 3.76 (dd, J=9, 7 Hz, 1H), 3.38 (m, 4 H), 3.16 (m, 1H), 3.11 (m, 2H), 2.13 (m, 2H), 2.06 (m, 1H), 2.01 (s, 3H); 13C NMR (DMSO-d6) δ 169.3, 160.6, 158 (d, J=246 Hz), 154.8, 153.8, 138.3 (d, J=8 Hz), 128.1, 125.2 (d, J=11 Hz), 113.7, 105.2 (d, J=26 Hz), 79.3, 71.7, 54.8, 50.3, 46.8, 43.1, 33.3, 29.8, 20.4; IR (diffuse reflectance) 2415, 2351, 2328, 1921, 1916, 1753, 1744, 1515, 1411, 1292, 1247, 1223, 1121, 1010, 983 cm−1. % Water (KF titration): 1.08.
