On June 20, 2005, Li, Xianjie; Li, Haibo; Tian, Wanli; Xu, Zheng published an article.Synthetic Route of 67914-60-7 The title of the article was Synthetic technology of 1-acetyl-4-(4-hydroxyphenyl)piperazine. And the article contained the following:
An important intermediate of antifungal drug ketoconazole, 1-acetyl-4-(4-hydroxyphenyl)piperazine [i.e., 1-[4-(4-hydroxyphenyl)-1-piperazinyl]ethanone], was synthesized from piperazine-6H2O and p-chloronitrobenzene by substitution, N- acetylation with acetic anhydride, reduction with Ni/hydrazine, diazotization, and hydrolysis in the presence of Cu/Cu(NO3)2, and its possibility of com. use was studied. The compound was obtained with yield excelled present route. The route may be used in com. production (no data). The experimental process involved the reaction of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone(cas: 67914-60-7).Synthetic Route of 67914-60-7
