Synthesis of ylidenhydrazides of [3-methyl-1-<i>n</i>-propyl- 7-(thietanyl-3)xanthinyl-8-thio]acetic acid
Ethyl ester of [3-methyl-1-<i>n</i>-propyl-7-(thietanyl- 3)xanthinyl-8-thio]acetic acid were synthesized by reaction of esterification of corresponding acid. Hydrazide of [3-methyl-1-<i>n</i>-propyl-7-(thietanyl- 3)xanthinyl-8-thio]acetic acid was obtained by interaction of ethyl ester with hydrasine hydrate. Ylidenhydrazides of [3-methyl-1-<i>n</i>-propyl-7- (thietanyl-3)xanthinyl-8-thio]acetic acid were synthesized with 57-65% yield by reaction of condensation of hydrasides with aromatic aldehydes. The structure of the synthesized compounds was confirmed by IR, 1H NMR spectroscopy data. The synthesized compounds are potentially biologically active substances.
