PROCEDURE

实验过程

To a 0° C. solution of (3S,4S)-5-acetyl-3-amino-4-methyl-1-((2-methylnaphthalen-1-yl)methyl)-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepine-7-carbonitrile hydrochloride (162 mg, 361 μmol) in DMF (1.2 ml) was added Boc-N-methyl-L-alanine (80.7 mg, 397 μmol), N,N-diisopropylethylamine (250 μl, 1.44 mmol), and HBTU (151 mg, 397 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-4-methyl-1-((2-methylnaphthalen-1-yl)methyl)-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (189 mg, 88%) as a white solid. MS m/z 620 (MNa)+.
