Abstract

Amides of 2-oxo- or 2-thiocinchoninic acid have been obtained by the reaction of substituted amides of 2-chlorocinchoninic acid with sodium acetate or sodium sulfide. The reaction of 2-thiocinchoninic acid amides with hydrazine hydrate or ethyl cyanoacetate leads to derivatives of 2-hydrazinocinchoninic acid or (4-carbamoyl-2-quinolyl)cyanoacetic ester respectively, which were also obtained from 2-chlorocinchoninic acid amides.
