Reaction Steps
To a suspension of hexane washed 60% sodium hydride (2.65, 66.0 mmol) in DMF (30 mL) at 0° C. was added 3-methoxyphenyl acetonitrile (8.0 g, 54.3 mmol). The reaction mixture was stirred at 0° C. for 30 min. A solution of 2,5-dibromopyridine (15.45 g, 65.2 mmol) in DMF(20 mL) was added and the reaction was stirred at room temperature for 20 min and at 50° C. for 30 min. To the reaction mixture was added H2O (20 mL) and Et2O (200 mL). The organic layer was washed with brine (5×50 mL), dried over Na2SO4 and concentrated. Purification by flash chromatography with hexanes/EtOAc (10:1) afforded 10.6 g of (5-Bromo-pyridin-2-yl)-(3-methoxy-phenyl)-acetonitrile. 1HNMR (400 MHz, CDCl3) δ 8.63 (s, 1H), 7.80 (dd, 1H), 7.27 (comp, 2H), 6.98 (d, 1H), 6.87 (s, 1H), 6.84 (m, 1H), 5.28 (s, 1H), 5.23 (s, 3H); MS (M+1) 303.0, 305.0.
