Reaction Steps

[2-(4-{(2R)-2-[((3S)(3-1,2,3,4-Tetrahydro-isoquinolyl))carbonylamino]-3-(4-chlorophenyl)-propanoyl}piperazinyl)phenyl]-N,N-dimethylcarboxamide was prepared according to the procedure described in Preparation XVI by using tert-butyl 3-[N-((1R)-2-{4-[2-(N,N-dimethylcarbamoyl)-phenyl]piperazinyl}-1-[(4-chlorophenyl)methyl]-2-oxoethyl)carbamoyl](3S)-1,2,3,4-tetrahydro-isoquinoline-2-carboxylate (Step 6) (156 mg, 0.23 mmol) and a satd soln of HCl in EtOAc (5 mL). The title compound was isolated by filtration as a white solid, and purified by preparative HPLC (TFA buffer) (125 mg). MS (ESI, pos.ion) m/z: 574 (M+H). Calc'd for C32H36ClN5O3: 573.25.
