FAUC-327
Chemical Name: 3-[4-(4-Chlorophenyl)piperazin-1-ylmethyl]pyrazolo[1,5-a]pyridine-7-carbonitrile
项目整合开发状态: Preclinical
项目研究机构: Friedrich-Alexander-Universit鋞 (Originator)
合成路线:Lithiation of 8-azaindole (I) with n-BuLi,followed by treatment with 1,2-diiodoethane (II) affords 7-iodopyrazolopyridine (III),which is then treated with CuCN,Pd2(dba)3 and diphenylphosphinoferrocene (dppf) in refluxing dioxane to provide pyrazolo[1,5-a]pyridine-7-carbonitrile (IV).Finally,Mannich condensation of (IV) with N-(4-chlorophenyl)piperazine (V) and formaldehyde gives rise to the title piperazinomethyl derivative.
