Reaction Steps

2-Butoxy-8-methoxy-9H-purin-6-amine trifluoroacetate salt (0.20 g) was dissolved in anhydrous N,N-dimethylformamide (5 mL) was treated with anhydrous potassium carbonate (0.315 g), heated to 60° C. for 1 hour and then cooled to room temperature. To the above was added 3-(bromomethyl)tetrahydrofuran (0.103 g) and the reaction mixture heated at 50° C., overnight. The reaction mixture was quenched with water (25 mL) and extracted into ethyl acetate (3 times, 100 mL combined total volume). The combined organic phase was separated and passed through a hydrophobic frit to dry. The organic phase was stripped to give a gum which was purified by C18 reverse phase chromatography using water (containing 0.1% formic acid)-acetonitrile (containing 0.05% formic acid) as eluant (20-60%) to afford the title compound as a white solid (97 mg).
