AbstractA convenient method for the synthesis of 2,4,8‐trisubstituted 1,7‐naphthyridines 6 by the reaction of (E)‐4‐(1‐aryl‐2‐methoxyethenyl)‐3‐isocyanopyridines 4, which could be easily prepared from commercially available 3‐aminopyridine via aroylation of lithium (4‐lithiopyridin‐3‐yl)pivalamide with N‐methoxy‐N‐methylbenzamides, with excess organolithiums has been developed.
