Procedure

2-Chloro-6-cyclohexylamino-purine (10 mmol), bromocyclopentane (20 mmol) and potassium carbonate (20 mmol, water free) in DMF (70 ml) are heated up to 50° C. and the mixture is stirred at this temperature for 10 hours. After cooling to RT the mixture is poured on water and extracted 3 times with ethyl acetate. The combined organic phases are washed twice with brine and the extract is dried over sodium sulfate and evaporated. A pale oil with Rf=0.36 (CH2Cl2/MeOH=20:1) is obtained.
