A mixture of 2-((3-fluoro-4-nitrophenoxy)methyl)-5-methylpyridine (2.0 g, 7.6 mmol), 4-bromobenzyl amine (1.6 g, 8.4 mmol), DIPEA (2.63 mL, 15.3 mmol) and acetonitrile (25.4 mL) were sealed in a reaction vessel and heated to 60° Celsius for 24 h. The mixture was cooled to RT, transferred to a round bottomed flask and concentrated to dryness. The crude mixture was heated to 70° Celsius in a minimum amount of i-PrOH until homogeneous and cooled to RT. The resulting mixture was filtered to collect the yellow solids which were dried to afford the title compound (2.82 g, 86%). MS (ESI): mass calcd. for C20H18BrN3O3, 427.053; m/z found, 428.0 [M+H]+.
