Reaction Steps

Argon was bubbled through a suspension of 2-methoxy-5-trifluoromethylphenylboronic acid (2.3 g, 10 mmol), 2-amino-4-bromopyridine (2.0 g, 12 mmol), and sodium carbonate (4.4 g, 42 mmol) in 1,4-dioxane (30 mL) and water (9 mL) for 15 minutes, then tetrakis(triphenylphosphine)palladium(0) (1.2 g, 1.0 mmol) was added. The resulting mixture was heated at 85° C. for 18 hours. The reaction mixture was cooled to ambient temperature then diluted with ethyl acetate and water. The phases were separated and the aqueous phase extracted with ethyl acetate then choloroform. The combined organic extracts were dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by silica gel column chromatography (0% to 10% methanol in chloroform gradient elution) to afford the title compound as yellow oil (3.22 g).
