PROCEDURE

实验过程

To a 0° C. solution of (3S,4S)-3-amino-1-((3-cyclopropylquinolin-4-yl)methyl)-4-methyl-2-oxo-5-(tetrahydro-2H-pyran-4-carbonyl)-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepine-7-carbonitrile dihydrochloride (60 mg, 103 μmol) in DMF (343 μl) was added Boc-N-methyl-L-alanine (23.0 mg, 113 μmol), N,N-diisopropylethylamine (89.1 μl, 515 μmol), and HBTU (43.0 mg, 113 μmol). The reaction was stirred at rt for 30 min, then diluted with 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)-7-cyano-1-((3-cyclopropylquinolin-4-yl)methyl)-4-methyl-2-oxo-5-(tetrahydro-2H-pyran-4-carbonyl)-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (55.3 mg, 77%) as a white solid. MS m/z 695 (MH)+.
