Reaction Steps
A biphasic mixture of water (3 mL) and toluene (10 mL) containing (4-bromo-3-fluoro-phenyl)-acetonitrile (457 mg, 2.14 mmol), sodium carbonate (1.00 g, 9.45 mmol), phenyl boronic acid (781 mg, 6.41 mmol) was sparged with nitrogen for 10 min, tetrakis(triphenylphosphine)palladium (250 mg) was added and the mixture heated to reflux for 48 hrs. After cooling, the solution was diluted with EtOAc, washed with water, the organic phase dried (MgSO4), filtered and evaporated to dryness. The residue was purified by column chromatography (0 to 10% EtOAc in hexanes) to afford (2-fluoro-biphenyl-4-yl)-acetonitrile as a colorless solid. 1H NMR (500 MHz, CDCl3) δ 7.54 (2H, m), 7.46 (3H, m), 7.40 (1H, m), 7.17 (2H, m), 3.79 (3H, s).
