Procedure
((3S)(3-1,2,3,4-Tetrahydroisoquinolyl))-N-[(1S)-1-[(4-chlorophenyl)methyl]-2-(4-{2-[(methylsulfonyl)amino]phenyl}piperazinyl)-2-oxoethyl]carboxamide (600 mg, 0.86 mmol) was prepared from the compound of Step 3 according to the procedure for Preparation XVI. The resulting crude material was diluted with EtOAc and washed with satd NaHCO3 soln. The organic layer was separated, dried over Na2SO4, filtered, and concentrated in vacuo. The resulting crude was purified by preparative HPLC (AcOH buffer) to afford the title compound (240 mg) as the acetate salt. MS (ESI, pos. ion) m/z: 596 (M+H), (ESI, neg. ion) m/z: 594 (M−H). Calc'd for C30H34ClN5O4S: 595.20 Anal. Calcd for C30H34ClN5O4S—C2H4O2—H2O: C, 57.01; H, 5.98; N, 10.39; Cl, 5.26. Found C, 57.69; H, 5.82; N, 10.54; Cl, 5.20.
