Respected sir, what about the disconnection of the C-O bond of ester where you formed an aniline derivative by breaking the C-N bond in one group disconnection, if we break the C-O bond (Forms the acylium ion) then that structure will also be stabilized by the conjugation of lone pairs of nitrogen.
Hello, You are right Sanket, I was just showing you one disconnection here, Other disconnection you have told will be used for the formation of C-O bond in esters. say you have access to para amino benzoic acid which is commercially available, from that you can esterify the ester and alkylate the amine functionality.
