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
