Versuchsvorschrift

A solution of tert-butyl (1S,2R)-2-(2-(2,4-dimethoxybenzyl)-7-fluoro-4-(1-methyl-1H-pyrazol-4-yl)-3-oxo-2,3-dihydro-1H-pyrrolo[3,4-c]pyridin-6-ylamino)cyclohexylcarbamate (2.4 g, 4.04 mmol) and TFA (5 mL, 64.9 mmol) was stirred at 80° C. for 30 min. The resulting suspension was diluted with EtOAc (5 mL) and filtered. The filtrate was evaporated in vacuo. The residue was diluted with H2O (300 mL) and EtOAc (100 mL) and filtered. The precipitate was washed with EtOAc and dried to give the title compound as a TFA salt (900 mg). The filtrate was extracted with EtOAc (200 mL). The aqueous phase was neutralized with saturated aq NaHCO3 solution and extracted with EtOAc (2×400 mL) and THF (2×200 mL). The organic phases were combined, dried over MgSO4, and evaporated. The residue was washed with EtOAc to give a first crop (400 mg) of the title compound as the free base. The TFA salt obtained above was diluted with saturated aq NaHCO3 solution (20 mL) and stirred at RT overnight. The resulting suspension was filtered and the solids were washed with EtOAc to give a second crop (700 mg) of the title compound as the free base (1.1 g, 79%).
