A mixture of 17.5 parts of 2-(4-methoxyphenyl)hydrazinecarbothioamide, 10 parts of acetic acid anhydride and 90 parts of dimethylbenzene is stirred and refluxed for one hour. The reaction mixture is allowed to cool to room temperature and 2,2'-oxybispropane and water are added. The precipitated product is filtered off and dried, yielding 14.5 parts (89%) of acetic acid 2-(aminothioxomethyl)-1-(4-methoxyphenyl)hydrazide.
