A schematic study on the condensation of 2,4‐dichloroquinolines (1) with 1‐naphthyamine (2) in the presence of CuI as a catalyst to functionalized mono (3) and di (4) substituted naphthylamino quinolines was described. Consequently, these mono‐ and di‐substituted amines on polyphosphoric acid‐catalyzed cyclization reaction with p‐toluic acid and acetic acid to yield the linear benzo[b]naphtho[2,1‐g][1,8]naphthyridines (5) and angular benzo[b]naphtho[2,1‐h] naphthyridines (6) in good yields. In addition to descried the similar synthesis of benzo[g]naphtho [2,1‐b][1,8]naphthyridines (12) and benzo[h]naphtho[2,1‐g][1,8]naphthyridines (13) from 2,4‐dichlorobenzo[h]quinoline (8) with various anilines (9) through my intermediates (10 and 11).
