A solution of tert-butyl 4-[5-(4-{(5S)-5-[(acetylamino)methyl]-2-oxo-1,3-oxazolidin-3-yl}-2-fluorophenyl)-2-pyridinyl]-1-piperazinecarboxylate (0.191 g, 0.372 mmol) in DCM (10 mL) and trifluoroacetic acid (10 mL) was stirred at room temperature for 3 h. The solvent was removed in vacuo and the residue was partitioned between EtOAc and 1 M NaOH solution. The organic layer was dried and evaporated to give the titled compound (0.150 g, 98%) as a colourless foam. APCI MS m/z 414 (M+H). 1H NMR (400 MHz, DMSO-d6) δ 8.30 (s, 1H), 8.22 (t, J=5.8 Hz, 1H), 7.72 (bdt, J=9.0, 2.1 Hz, 1H), 7.52-7.60 (m, 2H), 7.38 (dd, J=8.6, 2.1 Hz, 1H), 6.89 (d, J=9.0 Hz, 1H), 4.72-4.80 (m, 1H), 4.16 (t, J=9.0 Hz, 1H), 3.78 (dd, J=9.1, 6.7 Hz, 1H), 3.41-3.51 (m, 6H), 2.80-2.85 (m, 4H), 1.84 (s, 3H).
