Heterocyclization of the 2-aminoalkyl (and aryl) benzimidazoles under phase transfer catalysis conditions

Cherkaoui, O.,Essassi, E.M.,Zniber, R.

, p. 255 - 259 (2007/10/02)

A number of new imidazolo (pyrazino and diazepino) benzimidazoles have been prepared by reaction between 2-aminoalkyl (and aryl)benzimidazoles and dibromoalkanes Br-(CH2)n-Br under phase transfer catalysis conditions.These products have been characterized by 1H NMR, IR, MS and their microanalysis. --- Key words: heterocyclization / benzimidazole / diazepinobenzimidazole / benzimidazolo benzodiazepin
