실험 절차

4-[7-(2-Butynyl)-2,6-dioxo-2,3,6,7-tetrahydro-1H-purin-8-yl]piperazine-1-carboxylic acid tert-butyl ester (1.1 g) and potassium carbonate (0.43 g) were dissolved in N,N-dimethylformamide (15 ml), and chloromethyl pivalate (0.60 ml) was added to the solution while cooling on ice. After the mixture was stirred at room temperature overnight, the reaction mixture was diluted with ethyl acetate and washed with water. Insoluble white solid was collected by filtration, and washed with a mixture of hexane-ethyl acetate (1:1) to give 0.57 g of the title compound.
