Reaktionsschritte
to a stirred mixture of 180 parts of 1-[(4-methylphenyl)sulfonyl]-4-(2,4,6-trimethylphenyl)piperazine and 450 parts of water were added dropwise 675 parts of sulfuric acid. The whole was stirred and refluxed for 4 hours. After cooling, the whole was treated with an ammonium hydroxide solution. The product was extracted with dichloromethane. The extract was dried, filtered and evaporated, yielding 70 parts (69%) of 1-(2,4,6-trimethylphenyl)piperazine as a residue (intermediate 14).
