Versuchsvorschrift

(2R)-2-Amino-3-(3,4-dichlorophenyl)-1-(4-{2-[(methylsulfonyl)amino]phenyl}piperazinyl)propan-1-one was prepared according to the procedure for Preparation XVI using N-[(1R)-1-[(3,4-dichlorophenyl)methyl]-2-(4-{2-[(methylsulfonyl)amino]phenyl}piperazinyl)-2-oxoethyl](tert-butoxy)carboxamide (Step 1) (1.0 g, 1.8 mmol) and satd HCL in EtOAC. 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 (700 mg). MS (ESI, pos. ion) m/z: 471 (M+H), (ESI, neg. ion) m/z: 469 (M−H). Calc'd for C20H24Cl2N4O3S: 470.09. Anal. Calc'd for C20H24Cl2N4O3S: C, 50.96; H, 5.13; N, 11.88; Cl, 15.04. Found C, 50.66; H, 5.14; N, 11.51; Cl, 15.11.
