The sythesis of condensed imidazoles I. A simple synthesis of some 1,5-diaryl-3-[2-(4,5-dimethyl-benzimidazol-2-yl)]formazans and their derivatives
Original language description
The condensation reaction of 1,5-diaryl-3-formazylglyoxylic acids (1) with 4,5-diemthyl-1,2-diaminobenzene affords 1,5-diaryl-3-[2-(4,5-dimethyl-benzimidazol-2-yl)]formazanes (2) which were transformed by reductive splitting into 5,6-dimethyl-benzimidazol-2-carboxamid arylhydrazones (3). Oxidative cyclization of formazanes (2) leads to the 2,3-diaryl-5(4,5-dimethyl-benzimidazol-2-yl)-tetrazolium chlorides (4) and corresponding picrates (5) were also prepared.

Czech description
Kondenzační reakce 1,5-diaryl-3-formazylglyoxylových kyselin (1) s 4,5-diemthyl-1,2-diaminobenzenem poskytuje 1,5-diaryl-3-[2-(4,5-dimethyl-benzimidazol-2-yl)]formazany (2) které byly převedeny reduktivním štěpením na 5,6-dimethyl-benzimidazol-2-carboxamid arylhydrazones (3). Oxidativní cyklizace formazánů (2) vedla k 2,3-diaryl-5(4,5-dimethyl-benzimidazol-2-yl)-tetrazolium chloridům (4)
