PROCEDURE

实验过程

To a rt solution of tert-butyl methyl((S)-1-((2S,3S)-2-methyl-1-(2-(methylsulfonyl)acetyl)-4-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl)carbamate (60 mg, 121 μmol) in DMF (302 μl) was added 4-(bromomethyl)-7-methoxycoumarin (35.8 mg, 133 μmol), cesium carbonate (47.2 mg, 145 μmol), and sodium iodide (21.7 mg, 145 μmol). The reaction was stirred at rt for 8 h, then diluted with EtOAc, washed with H2O 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)-1-((7-methoxy-2-oxo-2H-chromen-4-yl)methyl)-4-methyl-5-(2-(methylsulfonyl)acetyl)-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (44.3 mg, 54%) as a white solid. MS m/z 707 (MNa)+.
