2-[(2-Cyclopropylethyl)oxy]-8-methoxy-9H-purin-6-amine trifluoroacetic acid salt (0.30 g) was heated with potassium carbonate (anhydrous, 0.46 g) in anhydrous DMF (5 mL) at 60° C. for 1 hour. The reaction was cooled to room temperature before 4-(bromomethyl) tetrahydro-2H-pyran (0.16 g) in anhydrous DMF (1 mL) was added. The reaction mixture was then heated to 50° C. overnight. The reaction was quenched into water (50 mL) and extracted with ethyl acetate (50 mL, 3 times). The organic layer was combined and washed with brine (50 mL). The organic layer was separated and dried by passing through a hydrophobic frit before being evaporated under reduced pressure to give oil). This material was purified by C18 reverse phase chromatography using water (containing 0.1% formic acid)-acetonitrile (containing 0.05% formic acid) as eluent (20-60%). This material was purified by reverse phase chromatography (20-60% acetonitrile: water). This gave the title compound as a white solid (0.1279 g).
