Participants

Reaction Steps

To a solution of 2-chloro-7,7-dimethyl-7,8-dihydro-6H-quinolin-5-one (0.35 g, 1.67 mmol) and 4-methoxyphenylamine (0.267 g, 2.2 mmol) in toluene (2 ml) under an argon atmosphere was added sodium tert-amylate (0.22 g, 2.0 mmol) and bis(tri-tert-butylphosphine)palladium (0.043 g, 0.084 mmol). The mixture was heated at reflux for 8 h. Then it was concentrated under reduced pressure and the residue was purified by column chromatography on silica gel to give the title compound (0.096 g, 19%) as a colorless solid.
