The initial compounds for the syntheses were 3-bromo-4-alkoxyphenylacetic acid hydrazides obtained using reactions between methyl esters of the corresponding acids and hydrazine hydrate [3]. The substituted benzylisothiocyanates were synthesized by reacting the corresponding benzyl chlorides with potassium rhodanate [4]. The target thiosemicarbazides I IX had the form of crystalline substances and
