Studies on pyrazine derivatives. Part XIII. synthesis and tuberculostatic activity of some 6-alkyl-amino- and 6-dialkylhydrazinopyrazine-2-carboxylic acids derivatives.

6-RNH- and 6-R2NNH-pyrazine-2-carbothioamides 1--3, 5, 6, 9 and 14 were obtained from 2-cyano-6-chloropyrazine. In the in vitro screening the thioamides were active against Myc. tuber.
