On August 31, 2008, Ukrainets, I. V.; Tkach, A. A.; Grinevich, L. A. published an article.HPLC of Formula: 92-36-4 The title of the article was 4-Hydroxy-2-quinolones 148. Synthesis and antitubercular activity of 1-hydroxy-3-oxo-6,7-dihydro-3H,5H-pyrido[3,2,1-ij]quinoline-2-carboxylic acid N-R-amides. And the article contained the following:
A method for the synthesis of the title compound [i.e., 1-hydroxy-3-oxo-6,7-dihydro-3H,5H-pyrido[3,2,1-ij]quinoline-2-carboxylic acid N-amides] is reported here. A reaction of 1,2,3,4-tetrahydroquinoline with methanetricarboxylic acid 1,1,1-tri-Et ester provided an ester compound [i.e., 2,3-dihydro-7-hydroxy-5-oxo-1H,5H-benzo[ij]quinolizine-6-carboxylic acid Et ester]. The above-mentioned amides were prepared from this intermediate by a reaction with primary amines. A comparative anal. has been carried out of the antitubercular activity of the compounds thus prepared with active structural analogs. The experimental process involved the reaction of 2-(4-Aminophenyl)-6-methylbenzothiazole(cas: 92-36-4).HPLC of Formula: 92-36-4
The Article related to tuberculostatic hydroxy oxo benzoquinolizinecarboxamide preparation, antibacterial antimycobacterial agent hydroxy oxo benzoquinolizinecarboxamide preparation, Heterocyclic Compounds (More Than One Hetero Atom): Pyrazines and Quinoxalines (Including Piperazines) and other aspects.HPLC of Formula: 92-36-4
