Procedure

In a 50 mL round-bottomed flask, tert-butyl (S)-1-((S)-1-((S)-2-(2-fluorophenylcarbamoyl)-2,3-dihydro-1H-pyrrolo[2,3-b]pyridin-1-yl)-3-methyl-1-oxobutan-2-ylamino)-1-oxopropan-2-yl(methyl)carbamate (39 mg, 72.0 μmol, Eq: 1.00) was combined with DCM (3.00 mL) to give a colorless solution. TFA (1.00 mL, 13.0 mmol, Eq: 180) was added the reaction was stirred at rt for 30 min and then 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-fluorophenyl)-1-((S)-3-methyl-2-((S)-2-(methylamino)propanamido)butanoyl)-2,3-dihydro-1H-pyrrolo[2,3-b]pyridine-2-carboxamide as an off-white solid (25 mg), m/z=442 (M+H).
