General description

N-Methyl-1,2-phenylenediamine is an ortho-diamine. In situ generated diazonium cations of N-methyl-1,2-phenylenediamine were used for the electrochemical modification of glassy carbon electrode.

Application

N-Methyl-1,2-phenylenediamine may be used in the following studies:
  • One-pot synthesis of 1-methyl-2(hetero)arylbenzimidazoles.
  • Preparation of 1-methyl-1H-benzimidazole-2(3H)-thione.
  • Total synthesis of the angiotensin II receptor antagonist, telmisartan.
  • Preparation of benzimidazoles from ketene dithioacetals.

An efficient synthesis of the angiotensin II receptor antagonist Telmisartan (1) is presented involving a cross coupling of 4-formylphenylboronic acid 10 with 2-(2-bromophenyl)-4,4-dimethyl-2-oxazoline (11) as the key step (90% yield). The benzimidazole moiety 15 was constructed regioselectively via a reductive

The electrochemically induced functionalization of glassy carbon electrode by aryl groups having an aliphatic amine group was achieved by reduction of in situ generated diazonium cations in aqueous media. The corresponding diazonium cations of 4-aminobenzylamine, 2-aminobenzylamine, 4-(2-aminoethyl)aniline, N-methyl-1,2-phenylenediamine, and N
