To a solution of 5-amino-2-bromo-4-chlorobenzotrifluoride (466 mg, 1.70 mmol) dissolved in DCM (1 mL) was slowly added a solution of 2-fluoropyridine-5-carbonyl chloride (270 mg, 1.70 mmol) in DCM (1 mL). A few drops of DMA were added and the reaction mixture was concentrated to form N-(4-bromo-2-chloro-5-trifluoromethyl-phenyl)-6-fluoro-nicotinamide as a purple solid.
