Reaction Steps
Prepared according to general Procedure F using 2,4-dichloro-8-fluoro-3-methylquinoline (250 mg, 1.1 mmol), 3-pyridylboronic acid (134 mg, 1.1 mmol), tetrakis(triphenylphosphine)palladium(0) (126 mg, 0.11 mmol), sodium carbonate (202 mg, 1.90 mmol) in toluene:water (5 mL:2 mL) and heating at 130° C. overnight. After purification 4-chloro-8-fluoro-3-methyl-2-(pyridin-3-yl)quinoline was obtained as a white solid. Mass Spectrum (ESI) m/e=273.0 (M+1).
