To tert-butyl ((S)-1-(((S)-1-(((S)-1-((S)-2-methyloxiran-2-yl)-1-oxo-3-phenylpropan-2-yl)amino)-1-oxo-3-(pyridin-2-yl)propan-2-yl)amino)-1-oxopropan-2-yl)carbamate (315 mg, 0.600 mmol) was added DCM (4 mL) followed by TFA (2 mL). The reaction mixture was allowed to stand for 2 h at which time it was concentrated to provide (S)-2-((S)-2-aminopropanamido)-N-((S)-1-((S)-2-methyloxiran-2-yl)-1-oxo-3-phenylpropan-2-yl)-3-(pyridin-2-yl)propanamide TFA salt as a yellow oil that was carried forward without further purification. MS (EI) for C25H28F3N4O5, found 425.3 [M-TFA]+.
