SYNTHESIS OF SYMMETRICAL TEREPHTHALOYL DERIVATIVES OF 2-(p-AMINOPHENYL)-5-AMINOBENZIMIDAZOLES - MONOMERS FOR THE PREPARATION OF POLYAMIDES

Various methods for the synthesis of symetrical terephthaloyl derivatives of 2-(p-aminophenyl)-5-aminobenzimidazoles were studied.Acylation of the isomeric aminonitro-2-phenylbenzimidazoles obtained in this research with subsequent reduction of the nitro groups was found to be the most preparatively convenient method.
