Versuchsvorschrift

A mixture of sodium carbonate (0.978 g), tetrakis(triphenylphosphine)palladium(0) (0.267 g), 4-butoxyphenylboronic acid (1.16 g) and 3-bromopyridin-2-amine (0.799 g,) in DME (23 mL) and water (4.6 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 (0.690 g) as a pale yellow solid.
