Abstract
2-[4-(2-bromoethoxy)phenoxy]ethanol(3) was prepared from 4-(benzyloxy)phenol by a three-step reaction.4-N-{2-[4-(2-hydroxyethoxy)phenoxy]ethyl}-1-N-tosylpiperazine(5) was successfully synthesized by the reaction of 3 with 1-N-tosylpiperazine.Finally,a novel compound,4-N-{2-[4-(2-thioethoxy)phenoxy]ethyl }-1-N-tosylpiperazine,was conveniently obtained by the introduction of the thioacetate group at 5,then by hydrolyzation in the presence of KOH.The structures were characterized by NMR,IR and MS.
