In a 100 mL round-bottomed flask, benzyl (S)-1-((S)-1-((S)-2-(2,6-difluorophenylcarbamoyl)-2,3-dihydro-1H-pyrrolo[2,3-b]pyridin-1-yl)-3-methyl-1-oxobutan-2-ylamino)-1-oxopropan-2-yl(2-(methylsulfonyl)ethyl)carbamate (33 mg, 48.1 μmol, Eq: 1.00) and 10% palladium on carbon (5.12 mg, 4.81 μmol, Eq: 0.1) were combined with MeOH (5 mL) to give a black suspension which was stirred under a hydrogen atmosphere (balloon) at rt for 1 h. The reaction mixture was filtered through Celite and the filtrate was concentrated in vacuo to give (S)-1-{(S)-2-[(S)-2-(2-methanesulfonyl-ethylamino)-propionylamino]-3-methyl-butyryl}-2,3-dihydro-1H-pyrrolo[2,3-b]pyridine-2-carboxylic acid (2,6-difluoro-phenyl)-amide (18 mg), m/z=552 (M+H).
