실험 절차

To a solution of 3-(3-bromo-phenyl)-6-chloro-1H-pyrazolo[3,4-d]pyrimidine (from Example 38 supra) (3.0 g, 9.7 mmol), Et3N (5.4 mL, 38.8 mmol) in DMF (50 mL), (2-(chloromethoxy)-ethyl)trimethylsilane (SEM-Cl, 2.0 mL, 11.6 mmol) was added in one portion. The resultant mixture was stirred for 30 minutes at room temperature. To this solution, 2-morpholino-ethanamine (1.51 g, 11.6 mmol) was added. The resulting mixture was stirred for one hour at room temperature. The reaction was poured into water (200 mL), extracted with EtOAc (3×200 mL), dried over Na2SO4, filtered and concentrated. The crude product was purified by chromatography (silica gel, 200-300 mesh, EtOAc) to give [3-(3-bromo-phenyl)-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazolo[3,4-d]pyrimidin-6-yl]-(2-morpholin-4-yl-ethyl)-amine as yellow oil. (Yield 1.7 g, 32.7%).
