Versuchsvorschrift

5,6-Diamino-1-propyl-1H-pyrimidine-2,4-dione hydrochloride salt (3.4 g) was dissolved in 80 mL of DMF along with 4-hydroxy-bicyclo[2.2.2]octane-1-carboxylic acid (2.5 g, 15 mmol). HATU (5.9 g, 1.05 eq) was added, followed by Et3N (8.30 mL, 4.05 eq). The resulting reaction mixture was stirred at rt overnight. The reaction mixture was filtered to remove some of the precipitate. The filtrate was concentrated under reduced pressure. The resulting residue was dissolved in 60 mL of H2O containing 10 eq of NaOH (5.9 g). The reaction mixture was stirred under reflux for 1 h, cooled to rt and acidified to pH2 with concentrated HCl. The resulting precipitate was collected by filtration and dried to afford 1.85 g of the xanthine derivative.
