実験手順
4-[7-(Benzyl)-3-methyl-2,6-dioxo-2,3,6,7-tetrahydro-1H-purin-8-yl]piperazine-1-carboxylic acid tert-butyl ester (182 mg) was dissolved in N,N-dimethylformamide (2 ml), and potassium carbonate (90 mg) and ethyl bromoacetate (0.06 ml) were added thereto. The reaction solution was stirred at room temperature overnight, diluted with ethyl acetate, and washed with water. The organic layer was dried over anhydrous magnesium sulfate, filtered, and the filtrate was concentrated under reduced pressure to give the title compound.
