A solution of the crude 2-(3-(5-bromo-2-chloro-7H-pyrrolo[2,3-d]pyrimidin-7-yl)propyl)isoindoline-1,3-dione in a mixture of THF and water (10 mL, 3:2, v/v) was added 5-aminopentanoic acid (172.3 mg, 1.47 mmol). The resulting mixture was heated at 150° C. under microwave irradiation for 1 h. After the solvent was removed, the residue was dissolved in a mixture of ethanol and water (20 mL, 3:2, v/v) followed by the addition of hydrazine (1.5 mL). Then the reaction mixture was heat at 80° C. for overnight. The solvent was removed and the residue was purified on HPLC to provide 5-((7-(3-aminopropyl)-5-bromo-7H-pyrrolo[2,3-d]pyrimidin-2-yl)amino)pentanoic acid as an clear oil (MS m/z 371.10 [M+H]+).
