Procedure

To a suspension of (3S)-ethyl 3-(3-chloro-5-(4-cyanotetrahydro-2H-pyran-4-yl)phenyl)-3-(2-(3-hydroxy-5-((5-hydroxy-1,4,5,6-tetrahydropyrimidin-2-yl)amino)benzamido)acetamido)propanoate (from step 2 above) (0.842 mmol, crude residue) in a mixture of acetonitrile/water (1:1) (6 mL) was added lithium hydroxide monohydrate (180.0 mg, 4.289 mmol) and the reaction mixture was stirred at room temperature overnight. The solvent was evaporated in vacuo to afford a yellow-orange viscous residue. The residue was dissolved in water (25 mL) and stirred with dichloromethane (50 mL). The aqueous layer was separated and acidified with TFA (1 mL in 3 mL ACN) and evaporated in vacuo to afford a pale orange viscous residue. The crude residue was purified by reverse-phase preparative HPLC on a Biotage 40+M (100 g) C18HS column and a gradient 10-60% acetonitrile in water containing 0.05% TFA to give the desired product, after lyophilization, as a colorless lyophilized powder (305 mg). LC-MS analysis of the solid shows the desired product's mass: m/z 599 (35ClM+H) and m/z 601 (37ClM+H); Calcd for C28H31ClN6O7:599.03.
