Abstract

THE TITLE compound 2 was obtained by treatment of 2,6-dihydroxypyromellitimide 1 with benzenesulphonyl chloride. Compound 2 was used as starting material for the synthesis of new dipyrimidine and dialkyl 2,5-di [(alkoxycarbonyl) amino] terephthalate derivatives. The reaction of 2 with different amines was intensively investigated with respect to the probability of isomerization.
