In this article, we report the synthesis of a series of new PEIs bearing triptycene groups based on a new dicarboxylic acid, bis(4-trimellitimido phenoxyjphenyl triptycene with several aromatic diols using tosyl chloride (TsCl)/N,N-dimethylformamide (DMF)/pyridine (Py) as condensing agent.
Starting with ethyl 5,7-dichloro-4-{[(4-methylphenyl)sulfonyl]amino}quinoline-2-carboxylate prepared by a previously reported method (Nichols and Yielding, 1993), a reaction was conducted using triphosgene and glycine to produce the corresponding tosyl derivative of [({[5,7-dicholor-2-(ethoxycarbonyl)quinolin-4-yl]amino}carbonyl)amino]acetic acid.
