Abstract

The reaction of 2-acetylthiophene with acetylthiophene with arenediazonium chlorides in the presence of cupric chloride as catalyst gives 2-acetyl-5-arylthiophenes. These products react with 5-chloro-and 5-bromoisatins to give 6-chloro-and 6-bromo-substituted 2-(5-aryl-2- thienyl)-4-quinolinecarboxylic acids.
