Novel 4‐amino‐6‐chloroquinoline‐3‐carbaldehyde has been synthesized by synchronous reduction by lithium aluminiumhydride and finally oxidation with MnO2. Friedländer condensation of it with reactive methylenes furnished novel benzo[3,4‐h][1,6]naphthyridine derivatives. J. Heterocyclic Chem., (2011).
