To a stirred solution of 1-((4R,5R)-5-{4-[6-(1-Amino-2,2,2-trifluoro-ethyl)-pyridin-3-yl]-phenyl}-4-fluoromethyl-2,2-dimethyl-oxazolidin-3-yl)-2,2-difluoro-ethanone (35 mg, 0.076 mmol) in CH2Cl2 (1 mL) is added trifluoroacetic acid (1 mL) at 0° C. then stirred to room temperature for 3 hours. The solvent evaporated in vacuo and the crude material is diluted with ammonia solution and extract with ethyl acetate. Organic layer is dried over sodium sulphate, solvent is evaporated in vacuo and purified by preparative TLC using in 70% ethyl acetate in hexane to afford the title compound (0.013 g): 1H-NMR (400 MHz, DMSO-d6) δ: 2.66 (d, J=7.28 Hz, 2H), 4.30-4.36 (m, 1.5H), 4.40-4.44 (m, 0.5H), 4.54-4.55 (m, 0.5H), 4.61-4.68 (m, 1.5H), 4.89 (t, J=3.8 Hz, 1H), 5.93 (d, J=4.36 Hz, 1H), 6.19 (t, J=53.8 Hz, 1H), 7.45 (d, J=8.32 Hz, 2H), 8.00 (d, 1.16 Hz, 2H), 8.05 (d, J=8.28 Hz, 2H), 8.73 (s, 1H), 8.84 (d, J=8.56 Hz, 1H). LC-MS (m/z): [M+H]=422.0.
