Procedure

A mixture of N2-butyl-8-(methyloxy)-3H-purine-2,6-diamine trifluoroacetate, (0.2 g, 0.571 mmol) and anhydrous potassium carbonate (0.316 g, 2.284 mmol) in DMF (2.5 ml) was heated at 50° C. for 1 hour. The mixture was cooled to room temperature and 4-(2-bromoethyl)-2,2-dimethyltetrahydro-2H-pyran (0.152 g, 0.685 mmol) was added and the mixture heated at 50° C. for 18 hours. The mixture was quenched with water (2 ml) and then extracted with DCM (2×5 ml). The DCM was separated through a hydrophobic frit and evaporated by blowing down under a stream of nitrogen. DMSO:MeOH (1:1) was added to the residue and the resulting precipitate was collected by filtration, washed with methanol and dried in vacuo to give the title compound as a white solid (136 mg).
