Two alternate synthetic routes are described for the synthesis of the hitherto unknown benzimidazo[1,2-c]indazolo[2,3-a]quinazoline (3). While dehydrative cyclisation of 2-[2-(2-azidobenzoylamino)-phenyl]benzimidazole (2) in polyphosphate ester gave

1, 3-dibenzyl-2-substituted-5-chloro benzimidazolines have been prepared from N, N 2 -dibenzyl-4-chloro-o-phenylenediamine and various aldehydes. Pyrolysis of these benzimidazolines yielded 1-benzyl-2-substituted-5-chloro-benzimidazoles, by preferent

The reaction of hydrazobenzene with benzylideneaniline in acetic acid gives dibenzylidenebenzidine. It has been shown that in this reaction, acetic acid functions as an acid catalyst causing benzidine rearrangement, while benzylideneaniline serves as
