A novel and efficient procedure for the synthesis of structurally diverse benzimidazolylquinolines has been realized through a new acid-catalyzed quinoxalinone-benzimidazole rearrangement of the spiro-quinoxalinone derivatives formed in situ from the reaction of 3-(2-aminophenyl)quinoxalin-2(1H)-ones and different ketones.

A protocol has been developed for the efficient synthesis of structurally diverse 4-(benzimidazol-2-yl)quinolines via reactions of 3-(2-aminophenyl)quinoxalin-2(1H)-ones and ketones, including acetone, acetophenones, 1,3-pentanedione and ethyl acetoacetat

The nitrogen atoms of the benzimidazole ring are alkylated initially in the quaternization of 2-(2-quinolyl)benzimidazole, and the nitrogen atom of the quinoline ring is alkylated only after this.Pyridyl- and quinolylbenzimidazoles and their quaternary sa
