Procedure
4-[7-(2-Methoxyphenyl)-1-(carboxymethyl)-3-methyl-2,6-dioxo-2,3,6,7-tetrahydro-1H-purin-8-yl]piperazine-1-carboxylic acid tert-butyl ester (3 mg) was dissolved in trifluoroacetic acid (0.5 ml), and the reaction mixture was stirred at room temperature for 30 minutes. After the solvent was removed, the residue was purified by reversed phase high performance liquid chromatography to give 4.14 mg of the title compound.
