실험 절차

To 80 parts of methanol are added 4.7 parts of 5-methyl-1-(4-nitrophenyl)-1H-1,2,4-triazole-3-thiol and 1.2 parts of sodium hydroxide and the whole is stirred till all solid enters solution. Then there are added 2.66 parts of dimethyl sulfate and stirring is continued for 1 hour at room temperature. 100 Parts of water are added. The precipitated product is filtered off, washed with water, dried, and crystallized from 2,2'-oxybispropane, yielding 3.3 parts (66%) of 5-methyl-3-(methylthio)-1-(4-nitrophenyl)-1H-1,2,4-triazole; mp. 121°-125° C.
