To a solution of 4-bromo-2-fluoro-5-trifluoromethoxy-phenylamine (500 mg, 2 mmol) dissolved in DCM (1 mL) was slowly added a solution of 2-fluoropyridine-5-carbonyl chloride (290 mg, 1.8 mmol) in DCM (1 mL). A few drops of DMA were added and the reaction mixture was concentrated to form N-(4-bromo-2-fluoro-5-trifluoromethoxy-phenyl)-6-fluoro-nicotinamide as a purple solid.
