Procedure

(2R)-2-Amino-3-(4-chlorophenyl)-1-(4-{2-[(cyclopropylmethyl) (methylsulfonyl)amino]phenyl}piperazinyl)propan-1-one was prepared according to the procedure for Preparation XVI using N-[(1R)-1-[(4-chlorophenyl)methyl]-2-(4-{2-[(cyclopropylmethyl)-(methylsulfonyl)amino]phenyl}-piperazinyl)-2-oxoethyl](tert-butoxy)carboxamide (Step 2) (560 mg, 0.95 mmol). 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 to afford 449 mg. MS (ESI, pos. ion) m/z: 491 (M+H), (ESI, neg. ion) m/z: 489 (M−H). Calc'd for C24H31ClN4O3S: 491.05.
