Versuchsvorschrift

N-[(1R)-1-[(3,4-Dichlorophenyl)methyl]-2-(4-{2-[(methylsulfonyl)amino]phenyl}piperazinyl)-2-oxoethyl]((3S)(3-1,2,3,4-tetrahydroisoquinolyl)) carboxamide was prepared from tert-butyl 3-{N-[(1R)-1-[(3,4-dichlorophenyl)methyl]-2-(4-{2-[(methylsulfonyl)amino]phenyl}piperazinyl)-2-oxoethyl]carbamoyl}(3S)-1,2,3,4-tetrahydroisoquinoline-2-carboxylate (Step 3) (590 mg, 0.80 mmol) 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 material was purified by preparative HPLC to give the title compound (477 mg) as the TFA salt. MS (ESI, pos. ion) m/z: 630 (M+H), (ESI, neg. ion) m/z: 628 (M−H). Calc'd for C30H33Cl2N5O4S: 629.16. Anal. Calcd for C30H33Cl2N5O4S-1.5C2HF3O2-0.5H2O: C, 48.89; H, 4.41; N, 8.64; Cl, 8.75. Found C, 49.33; H, 4.47; N, 8.94; Cl, 8.61.
