Reaction Steps
A flask was charged with 4-methoxyphenylboronic acid (1.0 g, 6.8 mmol), 5-bromo-2-chloropyridine (1.0 g, 5.2 mmol), Pd(PPh3)4 (50 mg, 0.043 mmol), potassium carbonate (1.08 g, 7.8 mmol), 1,4-dioxane (40 mL) and water (4 mL). The mixture was stirred at 100° C. under Argon for 20 h, and evaporated to afford a crude product. The crude product was purified by chromatography on silica gel (petroleum ether:ethyl acetate=40:1) to give the title compound (1.0 g, 88% yield) as white solids. MS: m/z 220.0 [M+H+].
