Reaction Steps

To a mixture of 4-(2-aminopyridin-3-yl)phenol (400 mg), 1-chloro-3-iodobenzene (615 mg), picoline acid (52.9 mg) and tripotassium phosphate (1368 mg) in DMSO (6 mL) was added copper (I) iodide (82.0 mg). The reaction mixture was stirred under a nitrogen atmosphere at 120° C. for 4 hr. To the reaction mixture was added water, 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 purified by silica gel column chromatography (ethyl acetate/hexane) and concentrated under reduced pressure to give the title compound (307 mg) as a yellow solid.
