Condensation of o-phenylenediamines (I) with 4-arylidene-2-substituted-oxazolin-5-ones (II) (azlactones) in acetic acid results in the formation of 3-benzyl-2(1H)quinoxalinones (III) and substituted benzimidazoles (IV).Structures of these compounds have been established based on their spectral data, and direct comparison with authentic samples prepared by unambiguous routes.
