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 (57 mg, 129 μmol) in DMF (321 μl) was added 1-(chloromethyl)-2-methylnaphthalene (29.4 mg, 154 μmol), cesium carbonate (54.4 mg, 167 μmol), and sodium iodide (25.0 mg, 167 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-4-methyl-1-((2-methylnaphthalen-1-yl)methyl)-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (56.3 mg, 73%) as a white solid. MS m/z 620 (MNa)+.
