Versuchsvorschrift

To a solution of 6-chloro-3-(2-methylsulfanyl-pyrimidin-4-yl)-1H-pyrazolo[3,4-d]pyrimidine (from Example 7 supra) (400 mg, 1.43 mmol) in 2-propanol (40 mL) was added N, N-dimethylethane-1,2-diamine (139 mg, 1.58 mmol) followed by triethylamine (159 mg, 1.57 mmol). The reaction mixture was stirred at reflux for 15 hours and the solvent was then removed under reduced pressure. The residue was extracted with dichloromethane (3×30 mL), washed with water (5 mL), dried over anhydrous sodium sulfate, filtered, and concentrated to afford N,N-dimethyl-N′-[3-(2-methylsulfanyl-pyrimidin-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-yl]-ethane-1,2-diamine (Yield 356 mg, 75%).
