A microwave vessel was charged with 2,4-dichloro-5,7-difluoro-3-methylquinoline (250 mg, 1.008 mmol), 2-naphthylboronic acid (225 mg, 1.310 mmol), tetrakis(triphenylphosphine)palladium(0) (87 mg, 0.076 mmol), sodium carbonate (534 mg, 5.04 mmol), toluene (8.06 mL), and water (2.02 mL). The mixture was heated at 100° C. for 2 h, then cooled to rt and partitioned between EtOAc and water. The organic layer was washed with brine, dried (MgSO4), and concentrated. The resulting crude material was purified by flash chromatography, eluting with a gradient of 0-6% EtOAc in hexane to give 4-chloro-5,7-difluoro-3-methyl-2-(naphthalen-1-yl)quinoline. Mass Spectrum (ESI) m/e=340.0 (M+1).
