Example 13 was repeated except that the 2,5-di(p-chloroanilino)-3,6-dihydroterephthalic acid dimethyl ester used in Example 13 was replaced with 7.56 parts of 2,5-dianilino-3,6-dihydroterephthalic acid dimethyl ester, to give 6.88 parts (98.9% of the theoretical yield) of 2,5-dianilinoterephthalic acid dimethyl ester.
