合成路线1

The condensation of N-benzylpiperazine (I) with ethyl isocyanate (II) in refluxing ether gives N-ethyl-4-benzyl-1-piperazinecarboxamide (III), which is debenzylated by hydrogenolysis with H2 over Pd/C in ethanol - HCl yielding N'-ethyl-1-piperazinecarboxarnide (IV). Finally, this compound is condensed with 1,1-bis(4-fluorophenyl)-4-chlorobutane (V) by means of NaHCO3 in refluxing ethanol.
