Labanauskas, Linas published the artcileSynthesis of 1-substituted 4-[4-(1H-indol-3-yl)butyl]piperazines, Safety of 2-Bromoethyl Methyl Sulfone, the publication is ARKIVOC (Gainesville, FL, United States) (2013), 363-376, 14 pp., database is CAplus.
A convenient synthetic route for preparation of various 4-[4-(1H-indol-3-yl)butyl]piperazines bearing heterocyclic and aliphatic substituents in position 1 has been developed. During this work, some synthetic possibilities of the common precursor, 4-[4-(1H-indol-3-yl)butyl]piperazine, were studied and evaluated.
