Reaction Steps

A mixture of sodium carbonate (906 mg), tetrakis(triphenylphosphine)palladium(0) (247 mg), 4-(1-methylethoxy)phenylboronic acid (1000 mg) and 3-bromopyridin-2-amine (0.739 g) in 1,2-dimethoxyethane (50 mL) and water (10 mL) was stirred under a nitrogen atmosphere at 80° C. overnight. The reaction mixture was added to water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (883 mg) as a pale-yellow solid.
