    OtherThe title compound was prepared

Procedure

The title compound was prepared according to the procedure described in Preparation XVI by using methyl 2-{4-[(2R)-2-({(3S)-2-[(tert-butyl)oxycarbonyl](3-1,2,3,4-tetrahydroisoquinolyl)}carbonylamino)-3-(4-chlorophenyl)propanoyl]piperazinyl}benzoate (Preparation XVII) (140 mg, 0.21 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 (62 mg). MS (ESI, pos.ion) m/z: 561 (M+H). Calc'd for C31H33ClN4O4: 560.22.
