A solution of 3-bromo-6-fluoro-2-methoxybenzamide (14 g, 61 mmol) in 100 mL of DMF was added 2,4,6-trichloro-[1,3,5]triazine (12.3 g, 67.0 mmol) portionwise at 0° C. and stirred for 2 hours before poured to ice/water. The white solid was collected by filtration and was washed with water, dissolved in DCM, dried over anhydrous Na2SO4 and concentrated to afford 3-bromo-6-fluoro-2-methoxybenzonitrile.
