Temperature140 °C

Reaction Steps

A mixture of picoline acid (0.427 g), tripotassium phosphate (11.04 g), copper (I) iodide (0.660 g), 7-methoxynaphthalen-2-ol (6.04 g), 3-bromopyridin-2-amine (3 g) and DMSO (50 mL) was stirred under a nitrogen atmosphere at 140° C. overnight. Water was added, and the mixture was filtered through celite, and the filtrate 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) and basic silica gel column chromatography (ethyl acetate/hexane) to give the title compound (1.667 g) as a pale-yellow solid.
