Procedure

Next, the NMP solution (β) of dimethyl pyromellitate was added to the NMP solution (α) of di-n-butyl 3,3′,4,4′-diphenylether-tetracarboxylate, and the flask containing them was cooled to 0° C., to which was dropwise added 17.13 g (0.144 mols) of thionyl chloride, and reacted therewith for 1 hour to obtain a mixed solution (γ) of di-n-butyl 3,3′,4,4′-diphenylether-tetracarboxylate dichloride and dimethyl pyromellitate dichloride.
