Reaction Steps

The 3,4-dicarbomethoxy-biphenyl-3′,4′-dicarboxylic acid obtained in Example 3-1 was reacted with concentrated hydrochloric acid to obtain 3,4,3′,4′-biphenyltetracarboxylic acid (s-BPTA). Then, the obtained 3,4,3′,4′-biphenyltetracarboxylic acid was reacted in acetic anhydride under heating, to obtain a 3,4,3′,4′-biphenyltetracarboxylic acid anhydride (s-BPDA).
