Reaction Conditions

Reaction Steps

At first, 10 g (44.3 mmol) of 1,3-dipropyl-5,6-diaminouracil was dissolved in 50 ml of pyridine, and 10.6 g (53.1 mmol) of adamantane-1-carbonylchloride was added by portions thereto at 0° C. After stirring for 30 minutes at 0° C., the mixture was concentrated under reduced pressure. A saturated aqueous sodium bicarbonate was added thereto. The residue was extracted with chloroform three times. The organic layers were combined, washed with a saturated aqueous sodium chloride, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. Then pyridine was removed from the residue by means of azeotropy with toluene to afford 19.5 g (yield: 100%) of 6-amino-5-(adamantane-1-carbonylamino)-1,3-dipropyluracil.
