To a flask containing (4′-(trifluoromethyl)-[1,1′-biphenyl]-4-yl)methanamine (107 g, 406 mmol) and 2-((3-fluoro-4-nitrophenoxy)methyl)-5-methylpyridine (114 g, 406 mmol) in acetonitrile (900 mL) was added DIPEA (106 mL, 610 mmol). The stirred mixture was then warmed to 80° Celsius and held for 7 h. After cooling to RT, the resulting slurry was diluted with acetonitrile (300 mL), filtered and the resulting solids were washed with acetonitrile (200 mL). The solids were dried in a vacuum oven at 75° Celsius for 3 h to give the title compound (147.5 g, 73%).
