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), 4-methylpyridine-3-boronic acid (0.28 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 45 h to give 4-chloro-5,7-difluoro-3-methyl-2-(4-methylpyridin-3-yl)quinoline as a brown solid. Mass Spectrum (ESI) m/e=305.0 (M+1).
