Procedure

The Suzuki coupled product was prepared according to Procedure F using 2,4-dichloro-5,7-difluoro-3-methylquinoline (0.50 g, 2.02 mmol), 6-ethoxypyridin-3-ylboronic acid (0.337 g, 2.02 mmol), palladium tetrakistriphenylphosphine (0.23 g, 0.20 mmol), potassium carbonate (0.56 g, 4.03 mmol) in toluene (4 mL) at 100° C. for 18 h to give 4-chloro-2-(6-ethoxypyridin-3-yl)-5,7-difluoro-3-methylquinoline as a white solid. Mass Spectrum (ESI) m/e=335.0 (M+1).
