Reaction Steps

A mixture of sodium carbonate (0.903 g), tetrakis(triphenylphosphine)palladium(0) (0.246 g), 4-(trifluoromethoxy)phenylboronic acid (1.14 g) and 3-bromopyridin-2-amine (0.737 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 (1.069 g) as a pale-yellow solid.
