実験手順
To a 0° C. solution of (3S,4S)-5-acetyl-3-amino-1-((2-methoxynaphthalen-1-yl)methyl)-4-methyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepine-7-carbonitrile hydrochloride (216 mg, 465 μmol) in DMF (1.55 ml) was added Boc-N-methyl-L-alanine (104 mg, 511 μmol), N,N-diisopropylethylamine (322 μl, 1.86 mmol), and HBTU (194 mg, 511 μmol). The reaction was stirred at rt for 30 min, then diluted with H2O and the solids were collected by vacuum filtration, taken up in EtOAc, washed with H2O, sat. aq. NaHCO3, and sat. aq. NaCl, dried over Na2SO4, filtered, and concentrated. The crude material was purified by flash chromatography to provide tert-butyl(S)-1-((3S,4S)-5-acetyl-7-cyano-1-((2-methoxynaphthalen-1-yl)methyl)-4-methyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (255 mg, 89%) as a white solid. MS m/z 636 (MNa)+.
