Reaction Steps

(2-{4-[6-(2-Morpholin-4-yl-ethylamino)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-pyrimidin-2-ylamino}-2-thiophen-3-yl-ethyl)-carbamic acid tert-butyl ester (200 mg, 0.35 mmol) was dissolved in EtOH (4 mL), then conc. HCl (4 mL) was added. The reaction mixture was stirred at room temperature for 15 hours. The solvent was removed under reduced pressure to afford the crude product which was purified by prep-HPLC to afford N1-{4-[6-(2-morpholin-4-yl-ethylamino)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-pyrimidin-2-yl}-1-thiophen-3-yl-ethane-1,2-diamine; hydrochloride. (Yield 17 mg, 8.4%).
