Verfahren zur Darstellung von phonyllerten und substituierten, phenyllerten 6. 6'-Dichinolyl-4.4'-dikarbonsäuren und Homologen.
Lässt man Anilin, Benzaldehyd und Brenztraubensäure aufeinander einwirken, so erhält man bekanntlich die 2-Phenylchinolin-4-karbonsäure. In ähnlicher Weise kann man die phenylierton 6. 6'-Dichinolyl-4.4'-dikarbonsäuren und Homologen darsteHfin, wenn man das Anilin durch Benzidin oder Tolidin oder Dianisidin ersetzt. Nimmt man an Stelle von Benzaldehyd substituierte Benzatdobyde, so goiangt, man zu entsprochendon Substttutions produkten.

Process for the preparation of phonyl-substituted and substituted, phenyl-substituted 6,6'-dichinolyl-4,4'-dicarboxylic acids and homologues.
If aniline, benzaldehyde and pyruvic acid are allowed to interact, it is known that 2-phenylquinoline-4-carboxylic acid is obtained. The phenylated 6,6'-dichinolyl-4,4'-dicarboxylic acids and homologues can be prepared in a similar manner if the aniline is replaced by benzidine or tolidine or dianisidine. If, in place of benzaldehyde, substituted benzate dobyds are used, then it is thought that substitution products are used.

insoluble and melts at 248.
One proceeds analogously if one starts out from tolidine and dianisidine.
Example 3: 106 g of toluidine and 106 g of benzaldehyde are in 1200 cm3 absolute
