Versuchsvorschrift

To a solution of [3-[6-(3-chloro-benzylamino)-pyridin-2-yl]-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazolo[3,4-d]pyrimidin-6-yl]-(2-morpholin-4-yl-ethyl)-amine (110 mg, 0.185 mmol) in dichloromethane (2.5 mL) was added TFA (2.5 mL). The reaction mixture was stirred for 2 hours at room temperature. The pH of the mixture was adjusted to about 8 with saturated NaHCO3 solution. The resulting mixture was extracted with ethyl acetate. The organic layer was dried and concentrated under reduced pressure. The residue was purified by column chromatography (silica gel, dichloromethane:MeOH, 20:1), then further purified by prep-HPLC to give {3-[6-(3-chloro-benzylamino)-pyridin-2-yl]-1H-pyrazolo[3,4-d]pyrimidin-6-yl}-(2-morpholin-4-yl-ethyl)-amine. (Yield 23 mg, 26%).
