Procedure

To a solution of 8-chloro-7-(2-propen-1-yl)-3,7-dihydro-1H-purine-2,6-dione (6 g, 26.5 mmol) in anhydrous DMF (30 ml) was added sodium carbonate (3.09 g, 29.15 mmol). After 10 minutes stirring at room temperature methoxyethoxymethylchloride (3.03 ml, 26.5 mmol) was added and stirring continued under nitrogen at room temperature for 66 hours. The reaction mixture was concentrated in vacuo and the residue dissolved in EtOAc (100 ml) and washed with brine (100 ml), the aqueous extract was extracted with DCM (100 ml) and the organic extracts dried (MgSO4) combined and concentrated in vacuo. The residue was trituated with EtOAc and the solid filtered off. Concentration of the filtrate afforded a light brown oil that was absorbed onto silica and purified by SPE (Si, 50 g) eluting with a gradient of 1:1 EtOAc/cyclohexane-EtOAc to afford the title compound as a white solid (2 g, 24%), m/z 315.2[MH+]
