Reaction Steps

8-Chloro-3-methyl-3,7-dihydropurine-2,6-dione (200 mg) and potassium carbonate (152 mg) were suspended in N,N-dimethylformamide (10 ml), and benzyl bromide was added dropwise thereto while cooling on ice. The reaction mixture was left standing till reaching room temperature, and was stirred at room temperature for 13 hours. The resulting white suspension was diluted with ethyl acetate and water, and filtered to give 133 mg of the title compound.
