Procedure

To a rt solution of tert-butyl(S)-1-((3S,4S)-1-((5-bromo-2-methoxynaphthalen-1-yl)methyl)-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 (33.8 mg, 45.3 μmol) in MeOH (45.3 μl) was added 2 M HCl in Et2O (181 μl). The reaction was stirred at rt for 3 h, then concentrated, taken up in H2O, and lyophilized to provide (S)-N-((3S,4S)-1-((5-bromo-2-methoxynaphthalen-1-yl)methyl)-4-methyl-5-(2-(methylsulfonyl)acetyl)-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-yl)-2-(methylamino)propanamide hydrochloride (29.0 mg, 94%) as a white solid. MS m/z 645/647 (MH)+.
