Heterocyclization of 3-[(1H-1,2,4-triazol-3-yl)thio]pentane-2,4-dione afforded 1-(6-methylthiazolo[3,2-b][1,2,4]-triazol-5-yl)ethan-1-one, the reactions of which with hydroxylamine, hydrazincarboxamide, hydrazincarbothioamide, hydrazine hydrate and para-toluenesulfonyl hydrazide resulted in the formation of the corresponding derivatives. 1-(6-Methylthiazolo[3,2-b][1,2,4]triazol-5-yl)ethan-1-one oxime reacted with alkyl halides and phenyl isocyanate to produce the corresponding O-alkyl- and O-phenylcarbamoyl derivatives. The growth regulating activity of the compounds obtained was studied.
