Two methods of preparation have been proposed and the synthesis has been effected of a large series of β-N-acylhydrazides of 1-R-4-hydroxy-2-oxo-1, 2-dihydroquinoline-3-carboxylic acids. The possibility of using various condensing agents for converting them into the corresponding 1,3,4-oxa-diazoloquinolines has been studied. Results are given of an investigation of the antitubercular activity of the synthesized compounds.
