To a stirred solution of (5-{4-[(4S,5R)-3-(2,2-Difluoro-acetyl)-4-fluoromethyl-2,2-dimethyl-oxazolidin-5-yl]-phenyl}-pyrimidin-2-ylmethyl)-carbamic acid tert-butyl ester (0.125 g, 0.253 mmol) in CH2Cl2 (10 mL) is added trifluoroacetic acid (1.0 mL) at room temperature. Resulting reaction mixture is allowed to stir at room temperature for 5 hours. The solvent evaporated in vacuo and the crude material is striped out with CH2Cl2 followed by washing with diethyl ether and dried in lipholiser to afford title compound (0.1 g): 1H NMR (400 MHz, DMSO-d6) δ: 4.31-4.33 (m, 1.5H), 4.36 (d, J=8.84 Hz, 2H), 4.42-4.46 (m, 0.5H), 4.56-4.57 (m, 0.5H), 4.66-4.70 (m, 0.5H), 4.92 (t, J=3.76 Hz, 1H), 5.98 (d, J=4.6 Hz, 1H), 6.20 (t, J=53.72 Hz, 1H), 7.52 (d, J=8.24 Hz, 2H), 7.84 (d, J=8.24 Hz, 2H), 8.36 (bs, 2H), 7.86 (d, J=8.84 Hz, 1H), 9.24 (s, 2H). LC-MS (m/z): [M+H]=354.9.
