Reaction Steps
To a solution of 2,5-dibromo-3-methylpyridine (5.0 g, 20. mmol) in N,N-dimethylformamide (20.0 mL, 259 mmol) was added copper cyanide (1.8 g, 20. mmol) and the reaction was stirred at 120° C. for 12 h. The reaction was partitioned between EtOAc and water. The organic layer was washed with brine, dried over sodium sulfate, filtered, concentrated and purified by combi-flash chromatography to afford 1.94 g (49% yield) of the desired product as a white solid.
