A mixture of 14.5 parts of acetic acid 2-(aminothioxomethyl)-1-(4-methoxyphenyl)hydrazide, 5 parts of sodium hydroxide and 80 parts of methanol is stirred and refluxed for 30 minutes. The reaction mixture is cooled and water is added. The whole is adjusted to pH 5 with a hydrochloric acid solution. The precipitated product is filtered off and dried, yielding 12.3 parts (91%) of 1-(4-methoxyphenyl)-5-methyl-1H-1,2,4-triazole-3-thiol.
