Reaktionsschritte

(R)-1-(3-Methoxypropyl)-2-(piperidin-3-yl)-1H-benzo[d]imidazole (0.29 mmol, 79 mg) in DMF (15 mL) was added to (R)-4-(4-bromophenyl)-3-(tert-butoxycarbonylamino)butanoic acid (0.32 mmol, 115 mg) and N-methylmorphine (1.16 mmol, 0.13 mL). The reaction mixture was stirred at rt for 5 min and then added HATU (0.32 mmol, 122 mg) and kept stifling at rt overnight. The reaction mixture was poured into H2O, extracted with EtOAc. The extract was washed with H2O, brine, dried over MgSO4 and filtered. The filtrate was concentrated in vacuo and purified by preparative LC/MS (35-60% CH3CN in H2O) to afford tert-butyl (R)-1-(4-bromophenyl)-4-((R)-3-(1-(3-methoxypropyl)-1H-benzo[d]imidazol-2-yl)piperidin-1-yl)-4-oxobutan-2-ylcarbamate (6A) (0.26 mmol, 160 mg, yield: 89.7%). ESI-MS: m/z 614.4 (M+H)+.
