実験手順
As shown in Scheme 3 above, a mixture of 2,6-dichloropurine (1.90 g, 10 mmol) and morpholine (2.34 g, 30 mmol) in water (25 mL) was heated under reflux for 15 min. Solidified reaction mixture was cooled to room temperature. Solid was filtered out and washed with water, methanol and ether. The 2-chloro-6-morpholin-4-yl-9H-purine was obtained in 96% yield (2.30 g). A mixture of 2-chloro-6-morpholin-4-yl-9H-purine (1.92 g, 8 mmol) and 2-(3,4-dimethoxyphenyl)ethylamine (4.35 g, 24 mmol) in sealed tube and under nitrogen was stirred at 190-195° C. for 1 hour. The reaction mixture turned to clear solution initially and then formed a slurry. The reaction mixture was cooled to room temperature diluted with methanol (8 mL) and the solid was collected by filtration, washed with methanol and Et2O and dried to afford 2.30 g (74% yield) of [2-(3,4-dimethoxy-phenyl)-ethyl]-(6-morpholin-4-yl-9H-purin-2-yl)amine.
