Reaction Steps

To a solution of 2-amino-7-benzyl-1H-purin-6(7H)-one (6.5 g, 26.86 mmol) in DMF (50 mL) was added potassium carbonate (5.6 g, 40.58 mmol), followed by 2-(trimethylsilyl)ethoxymethyl chloride (4.45 g, 27.08 mmol) at 0° C. The resulting mixture was stirred at 60° C. for 16 h. The mixture was diluted with water and filtered. The filter cake was washed with water twice, dried in vacuo to give 7-benzyl-3-((2-(trimethylsilyl)ethoxy)methyl)-1H-purine-2,6(3H,7H)-dione (10.8 g, 100% yield) as yellow oil. LCMS retention time 1.523 min; LCMS MH+-58 315.
