Procedure

A stirred solution of 1-((4R,5R)-5-{4-[6-(1-Benzylamino-2,2,2-trifluoro-ethyl)-pyridin-3-yl]-phenyl}-4-fluoromethyl-2,2-dimethyl-oxazolidin-3-yl)-2,2-difluoro-ethanone (0.22 g, 0.63 mmol) in methanol (10 mL) at room temperature is degassed with nitrogen for 10 minutes followed by addition of palladium on carbon (0.022 g, 0.0063 mmol). The reaction mixture is stirred at room temperature under hydrogen atmosphere for 16 hours. Reaction mixture is filter through celite, concentrated in vacuo. The crude material is purified by Combi flash eluting in 80% Ethyl acetate in Hexane afford the title compound (0.035 g). 1H-NMR (400 MHz, DMSO-d6) δ: 1.52 (s, 3H), 1.60 (s, 3H), 2.60-2.80 (m, 2H), 4.54-4.58 (m, 0.5H), 4.64-4.73 (m, 2H), 4.81-4.85 (m, 0.5H), 4.91-4.95 (m, 1H), 5.27 (d, J=3.6 Hz, 1H), 6.65 (t, J=52.44 HZ, 1H), 7.60 (d, J=8.28 Hz, 2H), 8.03 (m, 2H), 8.14 (d, J=8.32 Hz, 2H), 8.75 (s, 1H). LC-MS (m/z): [M+H]=462.0.
