Versuchsvorschrift

A mixture of (S)-3-amino-5-((6-bromo-2-methoxynaphthalen-1-yl)methyl)-2,3-dihydrobenzo[b][1,4]oxazepin-4(5H)-one hydrochloride (348 mg, 750 μmol), (S)-2-(tert-butoxycarbonylamino)butanoic acid (168 mg, 825 μmol), DIEA (519 μL, 3.00 mmol), and HBTU (313 mg, 825 μmol) in DMF (2.5 mL) was stirred at RT for 30 min. The mixture was diluted with EtOAc, washed with sat. NaHCO3, H2O, and brine brine, then dried over Na2SO4, and filtered. The filtrate was concentrated to give a residue that was purified by silica gel chromatography to provide tert-butyl (S)-1-((S)-5-((6-bromo-2-methoxynaphthalen-1-yl)methyl)-4-oxo-2,3,4,5-tetrahydrobenzo[b][1,4]oxazepin-3-ylamino)-1-oxobutan-2-ylcarbamate (431 mg, 94%) as a white solid. MS m/z 634/636 (MNa)+
