Reaction Steps

To tert-butyl 3-{N-[(1R)-2-(4-{2-[(dimethylamino)methyl]phenyl}piperazinyl)-1-[(4-chlorophenyl)methyl]-2-oxoethyl]carbamoyl}(3S)-1,2,3,4-tetrahydro-isoquinoline-2-carboxylate (Step 5) (0.31 g, 0.47 mmol) dissolved in dioxane (0.5 mL) was added 4N HCl in dioxane (1 mL). After stirring at RT for 6 h, the solvent was removed in vacuo, and the residue was purified by preparative HPLC (Waters Xterra C18 5 micron 100×20 mm, 10% to 80% CH3CN in H2O over 6.0 min, 4.63 min) to give N-[(1R)-2-(4-{2-[(dimethylamino)methyl]phenyl}piperazinyl)-1-[(4-chlorophenyl)methyl]-2-oxoethyl]((3S)(3-1,2,3,4-tetrahydroisoquinolyl))carboxamide (TFA salt) as a white solid (0.27 g). MS m/z: 560 (M+H). Calc'd for C32H38ClN5O2: 559.27. Anal. Calcd for C32H38ClN5O2-2.5 TFA-0.1 H2O: C, 52.47; H, 4.84; N, 8.27; Cl, 4.19. Found: C, 52.26; H, 4.75; N, 8.14; Cl, 4.41.
