Procedure

To a rt solution of tert-butyl(S)-1-((2S,3S)-7-cyano-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(methyl)carbamate (122 mg, 234 μmol) in DMF (585 μl) was added 5-bromo-1-(chloromethyl)-2-methoxynaphthalene (80.2 mg, 281 μmol), cesium carbonate (99.1 mg, 304 μmol), and sodium iodide (45.6 mg, 304 μmol). The reaction was stirred at rt for 1.5 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)-5-((5-bromo-2-methoxynaphthalen-1-yl)methyl)-7-cyano-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(methyl)carbamate (70 mg, 39% yield) as a white solid. MS m/z 792/794 (MNa)+.
