Reaction Steps

To a stirred solution of (2-morpholin-4-yl-ethyl)-[3-{3-[(thiophen-2-ylmethyl)-amino]-phenyl}-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazolo[3,4-d]pyrimidin-6-yl]-amine (170 mg, 0.3 mmol) in dichloromethane (10 mL) was added TFA (10 mL) at room temperature. The resulting mixture was stirred for another three hours at this temperature. The solvent was evaporated under reduced pressure and the residue was dissolved in EtOAc (10 mL). The organic phase was washed with saturated aqueous NaHCO3 (3 mL), brine (5 mL) and dried over anhydrous Na2SO4, filtered and concentrated. It was purified by prep-HPLC to give (2-morpholin-4-yl-ethyl)-(3-{3-[(thiophen-2-ylmethyl)-amino]-phenyl}-1H-pyrazolo[3,4-d]pyrimidin-6-yl)-amine as yellow solid. (Yield 20 mg, 11.7%).
