Abstract

The hydrolysis of the 1,2-amide bond by the action of acids and alkalis, monobromination, and condensation with aldehydes at the methylene group were investigated for 9-methyl(benzyl)-2-oxo-2,3-dihydroimidazo[1,2-a]benzimidazoles (I). After reduction of the 3-(o-nitro)benzylidene derivative obtained by this condensation, the amino group reacts with the 2-oxo group to give a five-ring system. The synthesis of 1-methyl-2-oxo-2,3-dihydroimidazo [1,2-a]benzimidazole is described.
