N-Alkyl-2-(substitutedbenzamido) benzamides and methyl 2-(2-(substitutedbenzamido) benzamido) alkanoates were prepared by either the reaction of amines or amino acid esters with benzoxazine derivatives or the DCC coupling of 2-substitutedbenzamido benzoic acid with amines or amino acid esters. Methyl 2-(2-(4-chlorobenzamido)benzamido alkanoates were used as the key intermediate for the preparation of dipeptide-coupled
