Reaction Steps

To a degassed solution of 2-bromo-6-chloro-4-methyl-pyridine (1.45 g, 7.04 mmol), 4-trifluoromethylbenzeneboronic acid (3.8 g, 20 mmol), 2N Na2CO3 (10 mL) in DME (80 mL) was added tetrakis(triphenylphosphine)palladium (690 mg, 0.6 mmol) under argon. The mixture was heated to 85° C. for 4 h, cooled to room temperature, diluted with water, and extracted with methylene chloride (3×). The organic solution was washed with brine, dried over Na2SO4, and concentrated. The residue was purified by column chromatography on silica gel (0-20% methylene chloride in heptane) to give the product as an off white solid (1.75 g, 65%). 1H NMR (300 MHz, CDCl3) δ 8.24 (d, J=7.91 Hz, 26H), 7.75 (d, J=8.29 Hz, 26H), 7.61 (s, 13H), 2.53 (s, 19H). MS m/e 382.2 (M+H)
