Reaction Steps
A mixture of sodium carbonate (307 mg), tetrakis(triphenylphosphine)palladium(0) (50.1 mg), 4-(cyclohexyloxy)phenylboronic acid (414 mg) and 3-bromo-5-chloropyridin-2-amine (300 mg) in DME (15 mL) and water (3 mL) was stirred at 80° C. for 5 hr. Silica gel was added and the mixture was concentrated in vacuo. The residue was purified by column chromatography (silica gel, eluted with EtOAc in hexane) to give the title compound (212 mg) as a yellow gum.
