(S)-Epichlorhydrin (V) was treated with benzylamine to afford aminoalcohol (VI). After protection of the amino group of (VI) as the tert-butyl carbamate (VII) with Boc2O, displacement of the chlorine of (VII) with arylpiperazine (I) furnished (VIII). Deprotection of the N-Boc group of (VIII) by means of trifluoroacetic acid gave (IX). Then, the N-benzyl group of (IX) was removed by transfer hydrogenolysis employing ammonium formate and Pd/C to provide the intermediate amine (IV).
