실험 절차

To a solution of 6-chloro-3-(2-methylsulfanyl-pyrimidin-4-yl)-1H-pyrazolo[3,4-d]pyrimidine (from Example 7 supra) (500 mg, 1.8 mmol) in 2-propanol (40 mL) was added tert-butyl 4-(aminomethyl)piperidine-1-carboxylate (420 mg, 2.0 mmol) followed by triethylamine (200 mg, 2.0 mmol). The reaction mixture was stirred at reflux for 15 hours. 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 4-{[3-(2-methylsulfanyl-pyrimidin-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino]-methyl}-piperidine-1-carboxylic acid tert-butyl ester. (Yield 700 mg, 85.3%).
