New series of ethyl 5-substituted 2,3-dihydro-3-oxoisothiazolo[5,4-b] pyridine-2-acetate was prepared either a) directly by reaction of 5-substituted 2-chlorothio-3-pyridinecarbonyl chlorides with ethyl glycinate or b) by oxidation of the correspondent 2-mercapto-3-pyridinecarboxamides. New 5-substituted 1,2-dihydro-2-thioxo-3-pyridinecarboxylic acids as starting materials are described.
