1-Acetyl-2,3-dihydrospiro[indolo-3, 2′-(1′,2′,3′, 4′-tetrahydroquinazolin-4′-one) was obtained from the reaction with anthranilamide, and 3-(2′-acetylaminophenyl)quinoxalin-2-one from the reaction with o-phenylenediamine, along with the normal products of the condensation of N-acetylindoxyl with substituted anilines. Derivatives of indolo[3,2-b]quinoline were synthesized from the obtained condensation products.
