To a stirred mixture of (S)-6-(benzyloxy)-N-((3-fluoro-4-(trifluoromethoxy)phenyl)(3-fluoropyridin-2-yl)methyl)-5-nitropicolinamide (800 mg, 0.0014 mol) in THF (8 mL), was added 10% Pd/C (800 mg, Aldrich). The reaction mixture was stirred under hydrogen atmosphere in the form of hydrogen bladder (˜20-22 PSI) for 12 h at room temperature. After completion of the reaction (monitored by TLC, 100% EtOAc), the reaction mixture was filtered through Celite® brand filter agent, the filtrate dried over anhydrous sodium sulfate and concentrated under reduced pressure to afford the title compound. 1H NMR (400 MHz, DMSO-d6) δ: 11.00 (s, 1H), 9.13 (d, J=6 Hz, 1H), 8.46 (d, J=4 Hz, 1H), 7.79 (t, J=9.2 Hz, 1H), 7.57-7.46 (m, 3H), 7.33 (d, J=8.4 Hz, 1H), 7.08 (br. s., 1H), 6.62 (d, J=7.6 Hz, 1H), 6.40 (br. s., 1H), 5.83 (br. s., 2H). MS (ESI, positive ion) m/z: 440.9 (M+H).
