Procedure

To a rt solution of tert-butyl(S)-1-((2S,3S)-1-acetyl-5-((3-cyclopropylquinolin-4-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 (65 mg, 108 μmol) in CH2Cl2 (434 μl) was added TFA (108 μl). The reaction was stirred for 2.5 h, then concentrated and purified by reverse phase preparative HPLC to provide, after extraction from sat. aq. NaHCO3 and lyophilzation, (S)-N-((2S,3S)-1-acetyl-5-((3-cyclopropylquinolin-4-yl)methyl)-2-methyl-4-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-yl)-2-(methylamino)propanamide (27.2 mg, 50%) as a white solid. MS m/z 500 (MH)+.
