Versuchsvorschrift

A mixture of 47.8 parts of 1-(4-isothiocyanatophenyl)-4-(4-methoxyphenyl)piperazine, 100 parts of hydrazine hydrate and 400 parts of 1,4-dioxane is stirred and refluxed for 1 hour. The reaction mixture is cooled and poured onto water. The precipitated product is filtered off, washed with water and with methanol and dried, yielding 46 parts (89%) of N-{4-[4-(4-methoxyphenyl)-1-piperazinyl]phenyl}hydrazinecarbothioamide.
