Alkylation of ethyl 1-piperazinecarboxylate (I) with 2-bromo-4'-chloroacetophenone (II) afforded disubstituted piperazine (III). Further cleavage of the carbamate group of (III) in refluxing HCl produced piperazine (IV). Bromide (VII) was prepared by reduction of 3,5-di-tert-butyl-4-hydroxybenzaldehyde (V) with NaBH4, followed by treatment of the resulting alcohol (VI) with PBr3. Piperazine (IV) was then condensed with bromide (VII) to give adduct (VIII). Finally, ketone reduction using LiAlH4 furnished the title alcohol.
