Participants

Reaction Steps

7-Allyl-8-chloro-3-methyl-3,7-dihydropurine-2,6-dione (420 mg) and 1-piperazine carboxylic acid tert-butyl ester (975 mg) were stirred at 150° C. for 50 minutes. After cooling to room temperature, the resulting reaction mixture was purified by silica gel column chromatography to obtain 584 mg of the title compound from a fraction eluted with ethyl acetate.
