실험 절차

4-[1-(Ethoxycarbonylmethyl)-3-methyl-2,6-dioxo-2,3,6,7-tetrahydro-1H-purin-8-yl]piperazine-1-carboxylic acid tert-butyl ester, 2-methoxyphenyl boronic acid (60 mg), and copper (II) acetate (200 mg) were dissolved in anhydrous tetrahydrofuran (5 ml), and pyridine (0.2 ml) was added thereto. The reaction mixture was stirred at room temperature for 3 days, filtered through a short column packed with NH-silica gel, and the filtrate was concentrated. The residue was purified by silica gel column chromatography to obtain 18 mg of the title compound from a fraction eluted with hexane-ethyl acetate (1:1).
