Procedure

A rt suspension of tert-butyl(S)-1-((2S,3S)-1-acetyl-5-((2-methoxynaphthalen-1-yl)methyl)-2-methyl-4-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (49.8 mg, 84.6 μmol) in 4 M HCl in dioxane (423 μl) was stirred for 2 h. The reaction was diluted with Et2O and the solids were collected by vacuum filtration, taken up in MeCN—H2O, and lyophilized to provide (S)-N-((2S,3S)-1-acetyl-5-((2-methoxynaphthalen-1-yl)methyl)-2-methyl-4-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-yl)-2-(methylamino)propanamide hydrochloride (32.4 mg, 73%) as a white solid. MS m/z 489 (MH)+.
