Reaction Steps

TFA (2 mL, 26.0 mmol, Eq: 96.7) was added to a solution of tert-butyl (S)-1-((S)-1-((S)-2-(2,6-difluorophenylcarbamoyl)indolin-1-yl)-3-methyl-1-oxobutan-2-ylamino)-1-oxopropan-2-yl(methyl)carbamate (0.15 g, 269 μmol, Eq: 1.00) in DCM (2 mL) and the resulting solution was stirred at rt for 1 hr. The reaction mixture was concentrated in vacuo and treated with minimal ether/hexanes to give (S)-1-[(S)-3-methyl-2-((S)-2-methylamino-propionylamino)-butyryl]-2,3-dihydro-1H-indole-2-carboxylic acid (2,6-difluoro-phenyl)-amide as a white solid (0.11 g), m/z=459 (M+H).
