摘要
The lithiated pyridine 7 on reaction with methyl 4-methylquinoline-3-carboxylate (8) gave the ketone 9, which could be converted to the biaryl 11 via an effective two step anellation procedure. Treatment of 11 with dilute sulfuric acid resulted in an unexpected ring closure to give the title ring system.
