Versuchsvorschrift

N-[(1R)-1-[(3,4-Dichlorophenyl)methyl]-2-(4-{2-[(methylsulfonyl)amino]phenyl}piperazinyl)-2-oxoethyl](tert-butoxy)carboxamide was prepared according to the procedure for Preparation XIX using (methylsulfonyl)(2-piperazinylphenyl)amine hydrochloride (800 mg, 2.8 mmol), N-Boc-D-3,4-dichlorophenylalanine (930 mg, 2.80 mmol) (Peptech), DIEA (480 μl, 2.80 mmol), EDC (1.66 g, 5.60 mmol), HOAT (400 mg, 3.0 mmol) and DMF (10 mL). The crude product was purified by flash chromatography (SiO2, 1:1 hexane:EtOAc) and concentrated in vacuo to afford the desired compound (1.0 g). MS (ESI, pos. ion) m/z: 571 (M+H), (ESI, neg. ion) m/z: 569 (M−H). Calc'd for C25H32Cl2N4O5S: 570.15.
