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 (84.6 mg, 202 μmol) in DMF (505 μl) was added 2-(3-(bromomethyl)-1H-indazol-1-yl)benzonitrile (75.7 mg, 243 μmol), cesium carbonate (85.6 mg, 263 μmol), and sodium iodide (39.4 mg, 263 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-((1-(2-cyanophenyl)-1H-indazol-3-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 (79 mg, 60%) as a white solid. MS m/z 672 (MNa)+.
