To a solution of 2-{[1-methyl-2-(methoxy)ethyl]oxy}-8-(methoxy)-9H-purin-6-amine trifluoroacetic acid salt (500 mg) in dry N,N-dimethylformamide (6.0 ml) at room temperature and under nitrogen was added potassium carbonate (0.75 g) in one go. The reaction was stirred at 60° C. for 1.5 hours. A solution of tetrahydro-2H-pyran-3-ylmethyl methanesulfonate (0.29 g) in dry N,N-dimethylformamide (1.0 ml) was added in one go and the reaction heated at 90° C. for 2 hours. The reaction was cooled to room temperature and then diluted with ethyl acetate (20 ml) and washed with water (10 ml). The organic layer was concentrated in vacuo. The product was purified by C18 reverse phase chromatography using water (containing 0.1% formic acid)-acetonitrile (containing 0.05% formic acid) as eluant (10-60%) to afford the title compound as a clear viscous oil (300 mg).
