反応手順
Tetrakis(triphenylphosphine)palladium(0) (36.3 mg) was added to a suspension of 3-bromo-5-fluoropyridin-2-amine (200 mg), 6-(cyclohexyloxy)pyridin-3-ylboronic acid (255 mg) and sodium carbonate (222 mg) in DME (5 mL) and water (1 mL) and the mixture was stirred at 90° C. under nitrogen for 3 hr. Water and EtOAc were added and the organic layer was separated, washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by column chromatography (silica gel, eluted with EtOAc in hexane) and washed with IPE to give the title compound (280 mg) as a yellow solid.
