Procedure

To a solution of tert-butyl 5-((5-chloro-2-((3-cyclopropyl-1-methyl-1H-pyrazol-5-yl)amino)pyrimidin-4-yl)amino)hexahydrocyclopenta[c]pyrrole-2(1H)-carboxylate (751.2 mg, 1.58 mmol) in DCM (15 mL) was added a solution of HCl in EtOAc (15 mL, 60 mmol). The reaction mixture was stirred at rt for 1 h and concentrated in vacuo. The residue was dissolved in water (30 mL) and adjusted to pH=10 with a saturated Na2CO3 aqueous solution, then extracted with DCM (100 mL×3). The combined organic phases were washed with brine (100 mL), dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The residue was purified by silica gel column chromatography (MeOH/DCM (v/v)=1/10) to give the title compound as a beige solid (0.29 g, 95%).
