A series of 2‐amino‐benzimidazoles with various substituents in position 1 and at the amino group has been prepared. The methods used are the displacement of chlorine by an amino group in the position 2 of the benzimidazole ring and the condensation of o‐phenylenediamines with carbodiimides or S‐methyl‐isothioureas.
