Versuchsvorschrift

175.3 g of sodium sulfoethylisothiocyanate was added to a solution obtained by adding 600 ml of methyl alcohol and 300 ml of water to 114.2 g of 1-acetyl-1-methylhydrazine. The system was then heated under reflux for 4 hours. After the reaction, the reaction solution was dried under reduced pressure. The resulting solid matter was then recrystallized from 1 l of methyl alcohol to obtain 169.4 g (yield: 66.0%) of the desired compound. m.p. 255°-256° C.
