In a 50 mL round-bottomed flask, tert-butyl (S)-1-((S)-1-((S)-2-(2-fluoro-6-(trifluoromethyl)phenylcarbamoyl)-2,3-dihydro-1H-pyrrolo[2,3-b]pyridin-1-yl)-3-methyl-1-oxobutan-2-ylamino)-1-oxopropan-2-yl(methyl)carbamate (20 mg, 32.8 μmol Eq: 1.00) was combined with DCM (1.5 mL) to give a colorless solution. TFA (500 μL, 6.49 mmol, Eq: 198) was added and the reaction mixture was stirred at rt for 30 min. The crude reaction mixture was concentrated in vacuo. The residue was taken up in DCM, washed with saturated aqueous NaHCO3, dried over Na2SO4 and concentrated in vacuo to give (S)—N-(2-fluoro-6-(trifluoromethyl)phenyl)-1-((S)-3-methyl-2-((S)-2-(methylamino)propanamido)butanoyl)-2,3-dihydro-1H-pyrrolo[2,3-b]pyridine-2-carboxamide as a white solid (10 mg), m/z=510.
