Abstract

A process for producing compounds of formula <FORM:1025910/C2/1> wherein the arylamino groups are in o-position to the carbalkoxy groups, Ar is phenyl or a polynuclear aryl radical which may be part of an aromatic heterocyclic system, R is a C1- 8 aliphat radical, R1 and R2 are H, halogen, nitro, alkyl or alkoxy and n is 1 or 2, comprises rearranging the bis(N-arylbenzimino ethers) of the corresponding dihydroxyphthalic acid esters* at 110-200 DEG C. The starting materials of the formula <FORM:1025910/C2/2> are made by reacting the disodium compounds of esters* with N-arylbenzimido chlorides.
