SYNTHESIS OF 4-AMINO DERIVATIVES OF 5,7-DICHLOROKINURENIC ACID THAT LED TO UNEXPECTED PRODUCTS VIA DETOSYLATION. Stephen Craig, Al Nichols, and Nagarajan Vasumathi, Dept. of Physical and Earth Sciences, Jacksonville State Univ., Jacksonville, AL 36265.
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 ...
