Reaction Steps

A mixture of 41 parts of 5-ethyl-3-(methylthio)-1-(4-nitrophenyl)-1H-1,2,4-triazole and 80 parts of methanol is hydrogenated at normal pressure and at room temperature with 1 part of palladium-on-charcoal catalyst 10%. After the calculated amount of hydrogen is taken up, the catalyst is filtered off and the filtrate is evaporated. The residue is crystallized from 1,1'-oxybisbutane. The product is filtered off and dried, yielding 33 parts (91%) of 4-[5-ethyl-3-(methylthio)-1H-1,2,4-triazol-1-yl]benzenamine; mp. 131.7° C.
