Abstract
The reaction of 4-chloro- and 4-chloro-6-methoxyquinoline-2-carbaldehydes with ophenylenediamine has given the corresponding 4-chloro-2-(benzimidazol-2′-yl)quinolines. 4-Methoxy-, 4-diethylamino-, 4-cyclohexylamino-, and 11 different 4-anilino-substituted 2-(2′-benzimidazol-2′-yl)quinolines have been synthesized from these by replacement of the halogen. A study of their UV spectra has shown that absorption at 310 nm is characteristic for the 4-anilino-2′-(benzimidazol-2′-yl)quinolines but not for the other 4-substituted derivatives. The compounds obtained form colored complexes with cuprous ions.
