(4-methoxyphenyl)boronic acid (1 g, 6.58 mmol), 5-bromo-6-methylpyridin-2-amine (1.23 g, 6.58 mmol), 1,1′-bis(diphenylphosphino)ferrocene-palladium dichloride dichloromethane adduct (537 mg, 0.658 mmol), potassium acetate (1.29 g, 13.16 mmol) and 1,4-dioxane (5 mL) were placed in a sealed tube and the mixture was subjected to microwave irradiation at 140° C. for 30 minutes. The resulting crude mixture was purified by flash column chromatography on SiO2 (Biotage 40+M cartridge, ethyl acetate) to afford 5-(4-methoxyphenyl)-6-methylpyridin-2-amine as a purple solid. LCMS calc.=214.11; found=215.17 (M+1)+.
