反応手順
2,6-Dichloropurine (1 mmol), powdered potassium carbonate (4 mmol) and cyclohexyliodide were vigorously stirred in 5 mL DMSO overnight. After evaporation of the solvent the product was extracted (water/diethylether) and purified by column chromatography (silicagel/1% MeOH in CHCl3). Crystallization from diethylether gave product in 41% yield, mp 116-121° C.
