N-Protection of 4-aminobutyric acid with Boc2O gives N-Boc-4-aminobutyric acid (II) , which by esterification with perphenazine (III) by means of either CDI in DMF or DCC and DMAP in CH2Cl2 affords the N-Boc-amino ester (IV). Alternatively, treatment of N-Boc-GABA (II) with t-BuCOCl in the presence of of Et3N in THF gives the mixed anhydride (V), which by reaction with perphenazine (III) in THF yields amino ester (IV) . Finally, compound (IV) is deprotected by means of MsOH in acetonitrile .
