Versuchsvorschrift
475 mg (3.29 mmol) of 4-(3-aminopropyl)morpholine was added to a 10 ml round bottom flask equipped with a magnetic stirring bar. The flask was heated to 100°-120° C. and 250 mg (1,06 mmol) of 3-(1,6-dihydro-6-oxo-9H-purin-9-yl)propionic acid, ethyl ester AIT-0027 was added to the stirring flask. Heating was continued for two hours. The solution was allowed to cool to room temperature and was then treated with 8 ml acetonitrile with stirring. A white precipitate formed and the solution was filtered after 20 minutes of stirring in acetonitrile. The filtrate was washed with acetonitrile and then with ether. This yielded 130 mg of a white solid. The mother liquor was allowed to stand overnight in a fume hood and was filtered the next day to yield another 100 mg of 3-(1,6-dihydro-6-oxo-9H-purin-9-yl)-N-[3-(4-morpholinyl)propyl]propanamide (AIT-0043). Yield: 65%. m.p. 145°-148° C.
