Reaction Steps
Tetrakis(triphenylphosphine)palladium(0) (40.8 mg) was added to a suspension of 3-bromo-5-methylpyridin-2-amine (220 mg), 4-phenoxyphenylboronic acid (327 mg) and sodium carbonate (249 mg) in DME (8 mL) and water (1.5 mL) and the mixture was stirred at 85° C. under nitrogen overnight. Silica-gel was added and the volatiles were removed in vacuo. The mixture supported on silica-gel was purified by column chromatography (NH-silica gel, eluted with EtOAc in hexane) to give the title compound (315 mg) as a white solid.
