摘要：

Treatment of ethyl 7-hydroxy-5-oxo-2,3-dihydro-1H,5H-pyrido[3,2,1-ij]quinoline-6-carboxylate with bromine in aqueous acetic acid solution gave not only the expected ethyl 2-bromo-1,3-dioxo-2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij]quinoline-2-carboxylate, but also an admixture of its 9-bromo-substituted isomer. The structural features of the major and minor reaction products are discussed.
