Procedure

To a solution of 3-bromopyridin-2-amine (1.0 g) in 1,2-dimethoxyethane (50 mL) were added naphthalen-2-ylboronic acid (1.292 g), sodium carbonate (1.225 g), tetrakis(triphenylphosphine)palladium(0) (0.334 g) and water (10 mL) at room temperature. The reaction mixture was stirred under a nitrogen atmosphere at 80° C. for 5 hr, water was added, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous sodium sulfate and the solvent was evaporated under reduced pressure. The residue was washed with acetonitrile to give the title compound (0.876 g).
