Versuchsvorschrift

2,6-Dichloro-9-(tetrahydrofuran-3-ylmethyl)-9H-purine (41 g) was dissolved in ethanol (200 ml) followed by the addition of morpholine (20 ml) and the resulting mixture was heated to reflux for 2 hours. The solvent was evaporated under reduced pressure, the residue was partitioned with ethyl acetate and saturated aqueous sodium bicarbonate solution, and the organic layer was washed with water and dried over magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography (hexane:ethyl acetate, 5:5 to 2:8 to 0:10) to give the title compound (41 g) as a white solid.
