A series of 11 substituted 2-(4-nitrophenyl)imidazolinones have been prepared by base catalyzed cyclizations of substituted 2-(4-nitrobenzoylamino)alkanamides. At higher methoxide concentrations the cyclization can be accompanied by reduction of nitro group to azoxy group. All the substances prepared have been identified by 1H and 13C NMR spectra.

Keywords: 2-Benzoylaminocarboxylic acid amides; 2-Phenyl-5-imidazolinones.
