100% | With benzotriazol-1-ol; triethylamine; diisopropyl-carbodiimide; In DMF (N,N-dimethyl-formamide); dichloromethane; | H-PHE-NH2 hydrochloride (114.2 mg, 200.7 g/mol, 0.57 mmol, 1 eq, Advanced ChemTech) was dissolved in 2 ml of dry DMF/DCM (1/1) and TEA (95 T, 101.19 g/mol, 0.73 G/CM3, 0.68 mmol, 1.2 eq) was added. After 30 mi- nutes, a DMF/DCM (1/1,4 ML) solution containing Fmoc-Dbu (Boc)-OH (250.2 mg, 440.5 g/mol, 0.57 mmol, 1 eq), DIC (89 LLI, 126.20 g/mol, 0.805 G/CM3, 0.57 mmol, 1 eq) and HOBt (77.6 mg, 135.12 g/mol, 0.57 mmol, 1eq) was added. After overnight stirring, solvent was evaporated and DCM (30 ML) was added. Organic phase was washed three times with water (10 ML) and once with brine (10 ml). Part of the product precipitated from the water phase and after filtration it was combined with the evaporated organic phase. 333 mg of 4-(N-Boc-amino)-N'-((S)-1-carbamoyl-2-phenylethyl)-(S)-2-(N''-Fmoc-ami- no) butanamide was obtained as a white powder with quantitative yield. |
