Reaction Steps

A mixture of sodium carbonate (799 mg), tetrakis(triphenylphosphine)palladium(0) (218 mg), 3-bromopyridin-2-amine (652 mg) and 5-phenylthiophen-2-ylboronic acid (1000 mg) in water (10 mL) and 1,2-dimethoxyethane (50 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 (579 mg) as a dark yellow solid.
