The CuI-assisted coupling between methyl N-(4-fluorophenyl)carbamate (I) and 1-bromo-4-fluorobenzene (II) produced the N,N-bis(4-fluorophenyl)carbamate (III), which was subsequently hydrolyzed to bis(4-fluorophenyl)amine (IV) using ethanolic KOH. Acylation of diarylamine (IV) with 3-bromopropionyl chloride (V) gave bromopropionamide (VI). This was then condensed with cis-2,6-dimethylpiperazine (VII) to yield the 3-piperazinylpropionamide (VIII). Amide reduction with LiAlH4 provided the triamino compound (IX). Acid chloride (XI), prepared from hydrocinnamic acid (X), was then coupled with piperazine (IX) to furnish amide (XII). The amide function was finally reduced to the corresponding amine by using LiAlH4.
