The lithium salts of quinoline-2-carboxylic acid and 4-methoxyquinoline-2-carboxylic acid undergo deprotonation at C3 when treated with LTMP in THF at -25 and 0degreesC, respectively. The lithium salts of quinoline-3- and 4-carboxylic acids Lire more prone to nucleophilic addition; nevertheless, they are deprotonated at C4 and C3, respectively, when treated with LTMP in THF at -50degreesC.
