Reaction Steps

To tert-butyl ((S)-1-(((S)-3-cyclopropyl-1-(((S)-1-((R)-2-methyloxiran-2-yl)-1-oxo-3-phenylpropan-2-yl)amino)-1-oxopropan-2-yl)amino)-1-oxopropan-2-yl)carbamate (380 mg, 0.779 mmol) was added DCM (2.5 mL) and TFA (2.5 mL). The mixture was allowed to stand at ambient temperature for 30 min before it was concentrated to provide (S)-2-((S)-2-aminopropanamido)-3-cyclopropyl-N-((S)-1-((R)-2-methyloxiran-2-yl)-1-oxo-3-phenylpropan-2-yl)propanamide TFA salt (377 mg, quant.) as a yellow oil that was carried forward without further purification. MS (EI) for C23H29F3N3O5, found 388.3 [M-TFA]+.
