Participants

Reaction Steps

2.66 g of [7-benzyl-2,6-dioxo-1,2,6,7-tetrahydropurin-3-yl]methyl 2,2-dimethylpropionate was dissolved in 30 ml of N,N-dimethylformamide, and 1.6 g of potassium carbonate and 1 ml of methyl iodide were added thereto. The mixture was stirred at room temperature overnight. The reaction mixture was diluted with ethyl acetate, and washed with water and 1N hydrochloric acid. The organic layer was dried over anhydrous magnesium sulfate, then filtered. The solvent was evaporated under reduced pressure. The residue was triturated with toluene. Thus, 2.16 g of the title compound was obtained.
