Diisopropyl Ether → 4-{4-[4-(4-methoxyphenyl)-1-piperazinyl]phenyl}-4H-1,2,4-triazole-3-thiol

Participants

Reaction Steps

A mixture of 23 parts of N-{4-[4-(4-methoxyphenyl)-1-piperazinyl]phenyl}hydrazinecarbothioamide, 23 parts of methanimidamide acetate and 80 parts of 1-butanol is stirred and refluxed for 1 hour. The reaction mixture is cooled and poured onto water. 2,2'-oxybispropane is added. The precipitated product is filtered off, washed with water and with methanol and crystallized from 1-butanol, yielding 17.7 parts of 4-{4-[4-(4-methoxyphenyl)-1-piperazinyl]phenyl}-4H-1,2,4-triazole-3-thiol; mp. 231.9° C.
