Procedure

N-[(1R)-2-(4-{2-[(2-Aminoethyl)amino]phenyl}piperazinyl)-1-[(4-chlorophenyl)methyl]-2-oxoethyl]((3S)(3-1,2,3,4-tetrahydroisoquinolyl))carboxamide was prepared according to Preparation XVI using tert-butyl 3-[N-((1R)-2-{4-[2-({2-[(tert-butoxy)carbonylamino]-ethyl}amino)phenyl]-piperazinyl}-1-[(4-chlorophenyl)-methyl]-2-oxoethyl)-carbamoyl](3S)-1,2,3,4-tetrahydro-isoquinoline-2-carboxylate (150 mg, 0.18 mmol) and 25 mL of EtOAc satd with HCl. The crude product was concentrated to provide the desired product (90 mg). MS (ESI, pos. ion) m/z: 561 (M+H), (ESI, neg. ion) m/z: 559 (M−H). Calc'd for C31H37ClN6O2: 560.27.
