2-(Tributylstannyl)pyridine → HCID 59631359, compound

Participants

Reaction Steps

The stille coupled products were prepared according to Procedure E using a mixture of 2,4,6-trichloro-7-fluoro-3-methylquinoline and 2,4,6-trichloro-5-fluoro-3-methylquinoline (0.50 g, 1.90 mmol), 2-(tributylstannyl)pyridine (0.77 mL, 2.08 mmol), palladium tetrakistriphenylphosphine (0.22 g, 0.19 mmol) in toluene (1.90 mL) to give 4,6-dichloro-7-fluoro-3-methyl-2-(pyridin-2-yl)-quinoline as a white solid. Further elution gave 4,6-dichloro-5-fluoro-3-methyl-2-(pyridin-2-yl)quinoline as a white solid. Mass Spectrum (ESI) m/e=307.0 (M+1). Further elution gave 4-chloro-7-fluoro-3-methyl-2,6-di(pyridin-2-yl)-quinoline.
