Reaction Steps
To a degassed solution of 4-bromo-3-fluorotoluene (50.0 g, 264 mmol) in 500 mnL of DMF was added Zn(CN)2 (18.6 g, 159 mmol) and Pd(PPh3)4 (6.1 g, 5.3 mmol). The reaction was stirred at 80° C. for 6 hours, then cooled to room temperature. The solution was poured into EtOAc, washed with water, sat. aq. NaHCO3, and brine, then dried (Na2SO4), filtered, and concentrated in vacuo to provide the crude product. Purification by silica gel chromatography (0-5% EtOAc/hexane) provided the titled product.
