실험 절차

To a solution of 8-chloro-3-(2-methylsulfanyl-pyrimidin-4-yl)-imidazo[1,2-a]pyrazine (from Example 44 supra) (400 mg, 1.44 mmol) in iPrOH (20 mL) was added 2-morpholino-ethanamine (244 mg, 1.88 mmol) followed by diisopropylethylamine (242 mg, 1.88 mmol). The reaction mixture was stirred at reflux for 15 hours and the solvent was removed under reduced pressure. The residue was extracted with dichloromethane (150 mL) and washed with water (3×25 mL), dried over anhydrous sodium sulfate and concentrated to afford [3-(2-methylsulfanyl-pyrimidin-4-yl)-imidazo[1,2-a]pyrazin-8-yl]-(2-morpholin-4-yl-ethyl)-amine. (Yield 410 g, 76.8%). LC-MS: [M+H]+ 372.
