실험 절차

A mixture of sodium carbonate (122 mg), tetrakis(triphenylphosphine)palladium(0) (33.2 mg), 4-phenoxyphenylboronic acid (160 mg) and 4-chloro-3-iodopyridin-2-amine (146 mg) in DME (10 mL) and water (3 mL) was stirred at 80° C. overnight. The mixture was added with silica gel, concentrated in vacuo, and purified by column chromatography (silica gel, eluted with EtOAc in hexane) to give the title compound (111 mg) as a pale yellow solid.
