Procedure
8-Chloro-3-methyl-7-(3-methylbut-2-enyl)-3,7-dihydropurine-2,6-dione (40 mg) and 1-homopiperazine carboxylic acid tert-butyl ester (87 μl) were stirred at 140° C. for 1 hour, then trifluoroacetic acid (0.5 ml) was added thereto, and the reaction mixture was stirred at room temperature for 30 minutes. After removing the solvent by distillation at reduced pressure from the reaction mixture, the residue was purified by HPLC with a reversed phase column using water-acetonitrile-trifluoroacetic acid system as eluent to give 46.8 mg of the title compound.
