Reaction Steps
Following the above procedure, 4,5-dichloro-o-phenylenediamine was reacted with 2-ketoglutaric acid in ethanol to yield 6,7-dichloro-3,4-dihydro-3-oxo-2-quinoxaline propionic acid. Reaction of the free acid with ethanol in the presence of BF3 etherate yielded the corresponding ethyl ester, β-(6,7-dichloro-3,4-dihydro-3-oxo-2-quinoxaline)propionic acid, ethyl ester melting at 183.5-184.5. The free acid had the following analysis.
