実験手順

A mixture of 20 parts of 4-[5-methyl-3-(methylthio)-1H-1,2,4-triazol-1-yl]benzenamine, 15 parts of Raney-nickel catalyst and 400 parts of methanol is stirred and refluxed for 2 hours. The Raney-nickel is filtered off and another 15 parts of the catalyst are added. Stirring at reflux is continued for 4 hours. The reaction mixture is filtered, washed on the filter with methanol and the filtrate is evaporated. The residue is crystallized from a mixture of 4-methyl-2-pentanone, 2,2'-oxybispropane and petroleumether. The product is filtered off and dried, yielding 7.6 parts (47%) of 4-(5-methyl-1H-1,2,4-triazol-1-yl)benzenamine; mp. 145° C.
