Procedure

To a rt solution of tert-butyl(S)-1-((2S,3S)-1-acetyl-2-methyl-4-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (100 mg, 239 μmol) in DMF (597 μl) was added (3-cyclopropylquinolin-4-yl)methyl methanesulfonate (79.5 mg, 287 μmol), cesium carbonate (101 mg, 311 μmol), and sodium iodide (46.6 mg, 311 μmol). The reaction was stirred at rt for 16 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-((2S,3S)-1-acetyl-5-((3-cyclopropylquinolin-4-yl)methyl)-2-methyl-4-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (65 mg, 45%) as a white solid. MS m/z 600 (MH)+.
