Procedure

To a rt solution of tert-butyl(S)-1-((3S,4S)-1-((5-bromo-2-methoxynaphthalen-1-yl)methyl)-7-cyano-4-methyl-5-(2-(methylsulfonyl)acetyl)-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (32 mg, 41.5 μmol) in CH2Cl2 (166 μl) was added TFA (41.5 μl). The reaction was stirred at rt for 6 h, then concentrated, taken up in H2O, and lyophilized to provide (S)-N-((3S,4S)-1-((5-bromo-2-methoxynaphthalen-1-yl)methyl)-7-cyano-4-methyl-5-(2-(methylsulfonyl)acetyl)-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-yl)-2-(methylamino)propanamide 2,2,2-trifluoroacetate (30.3 mg, 93%) as a white solid. MS m/z 670/672 (MNa)+.
