Reaction Steps
To a solution of 5-bromo-2-(bromomethyl)-1,3-difluorobenzene (1.6 g, 5.60 mmol) in DMF (20 mL) was added KCN (0.401 g, 6.16 mmol). The resulting mixture was stirred at 25° C. for 16 h. The mixture was dissolved in H2O (50 mL) and extracted by EA (50 mL). The organic layer was dried over Na2SO4, filtered and concentrated. The crude material was purified by silica column chromatography (PE/EA=3/1) to yield a white solid of 2-(4-bromo-2,6-difluorophenyl)acetonitrile (1.1 g, 2.57 mmol, 45.9% yield): 1H NMR (400 MHz, CD3OD) δ 7.39-7.36 (m, 2H), 3.89 (s, 2H).
