Reaction Steps
To a stirred solution of the above benzamide intermediate (9.4 g, 40 mmol) in DMF (15 mL) was added cyanuric chloride (7.24 g, 40 mL) at 0° C. The reaction was stirred at 0° C. for 3 h. Water was added slowly to the reaction and it was extracted with CH2Cl2 (3×100 mL). The solvent was washed with brine and dried over Na2SO4. The solvent was removed to give 4-bromo-2,6-difluorobenzonitrile (7.57 g, 86.9%).
