5-((5-Methylpyridin-2-yl)methoxy)-2-nitro-N-((4'-(trifluoromethyl)-[1,1'-biphenyl]-4-yl)methyl)aniline → 5-((5-methylpyridin-2-yl)methoxy)-N1-((4'-(trifluoromethyl)-[1,1'-biphenyl]-4-yl)methyl)benzene-1,2-diamine

Reaction Steps

To a high pressure reactor were added 5-((5-methylpyridin-2-yl)methoxy)-2-nitro-N-((4′-(trifluoromethyl)-[1,1′-biphenyl]-4-yl)methyl)aniline (147 g, 297 mmol), 5% Pt/C (23.2 g, 2.97 mmol), and THF (2.5 L). The reactor was flushed with nitrogen and then stirred under an atmosphere of H2 (135 psi) for 24 h. The mixture was then filtered through celite and the filtrate was concentrated to dryness to afford the title compound as a tan solid (134 g, 97%).
