Treatment of 6,7-dichloro-5,8-quinoxalinedione (I) with sodium azide in AcOH afforded azide (II), which was reduced to amine (III) using NaBH4. Acetylation of (III) with Ac2O and a catalytic amount of H2SO4 yielded amide (IV). Subsequent reaction of (IV) with 4-bromoaniline (V) produced the corresponding (4-bromophenyl)aminoquinoxaline (VI). Finally, conversion of (VI) into the target imidazole was performed by treatment with NaOH in refluxing EtOH.
