Reaction Steps
To a stirred solution of (S)—N-((3-fluoro-4-(trifluoromethoxy)phenyl)(3-fluoropyridin-2-yl)methyl)-4-hydroxy-5-nitropicolinamide (0.35 g, 0.0007 mol) in MeOH (10 mL) was added Raney Ni (0.3 g, Monarch), followed by hydrazine hydrate (2 mL, Aldrich) added in a drop-wise fashion at rt. The reaction mixture was stirred for 3 h. After completion of the reaction (monitored by TLC, 50% EtOAc in hexane), the reaction mixture was filtered through Celite® brand filter agent and concentrated providing a residue. The residue was triturated with Et2O, filtered dried under vacuum to give the title compound as a brown solid. 1H NMR (DMSO-d6) δ: 9.41 (d, J=7.5 Hz, 1H), 8.55 (d, J=4.2 Hz, 1H), 7.83-7.78 (m, 2H), 7.54-7.44 (m, 3H), 7.27 (d, J=9.9 Hz, 2H), 6.46 (d, J=6.9 Hz, 1H), 5.29 (s, 2H).
