Methyl‐3‐(2‐chloroquinolin‐3‐yl)acrylates 5a‐i on reaction with methyl amine in acetonitrile yielded methyl‐3‐[2‐(methylamino)quinolin‐3‐yl]acrylates 6a‐i . When, these were followed by the reaction with the Vilsmeier reagent, they afforded methyl benzo[ b ][1,8]naphthyridin‐3‐carboxylate 7a‐i in good yields.
