Abstract Various 4‐substituted benzo[ c ][2,7]naphthyridines were prepared from the corresponding 4‐chloro derivative by Pd(0) coupling reaction or nucleophilic substitution. More particularly, 4‐aroyl‐benzo[e][2,7]naph‐thyridines were synthesized by aroylation with arenecarbaldehydes in the presence of 1,3‐dimethylimida‐zolium iodide.
