Versuchsvorschrift

To a rt solution of tert-butyl(S)-1-((2S,3S)-1-acetyl-8-cyano-2-methyl-4-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (53 mg, 120 μmol) in DMF (299 μl) was added 1-(chloromethyl)-2-methoxynaphthalene (29.6 mg, 143 μmol), cesium carbonate (50.6 mg, 155 μmol), and sodium iodide (23.3 mg, 155 μmol). The reaction was stirred at rt for 1 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)-5-acetyl-7-cyano-1-((2-methoxynaphthalen-1-yl)methyl)-4-methyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (60 mg, 82%) as a white solid. MS m/z 636 (MNa)+.
