The 3-(2-acetylamino-5-chlorophenyl)-1,2-dihydro-quinoxaline-2-one (III) was prepared by the reaction of 5-chloro-N-acetylisatine (I) with 1,2-diaminobenzene. The 3-(2-acetylamino-5-chlorophenyl)-6,7-dimethyl-1,2-dihydro-quinoxaline-2-one (IV) was prepared analogically to compound (III) from 5-chloro-N-acetylisatine (I) and 4,5-dimethyl-1,2-diaminobenzene. The corresponding amino derivative (VII) and (VIII) was then prepared by alkaline hydrolysis of compounds (III) and (IV). Cyclization of these aminoderivatives (VII) and (VIII) afforded derivatives of indolo[2,3-b]quinoxaline (XI) and (XII). The 5-bromo-N-acetylisatine (II) was prepared analogically to compound (I), the 3-(2-acetylamino-5-bromophenyl)-1,2-dihydro-quinoxaline-2-one (V), resp. 3-(2-acetylamino-5-bromophenyl)-6,7-dimethyl-1,2-dihydro-quinoxaline-2-one (VI) was prepared analogically to compound (III), resp.
