Versuchsvorschrift

6.2 g of 3,7-diethylxanthine, 4.1 g of ptassium carbonate, and 6.6 g of 1-bromo-6-hydroxy-6-methylheptane are stirred in 100 ml of dimethylformamide at 120° C. for 18 hours. The mixture is filtered hot with suction, the filtrate is concentrated under recuced pressure final recrystallization from diisopropylether with addition of petroleum ether.
