Reaktionsschritte

1-(5,6-Oxidohexyl)-3,7-dimethylxanthine was synthesized as follows: A mixture of 1-bromohexene (10.7 g, 66 mmol), sodium hydride (1.58 g, 66 mmol), and theobromine (11.9 g, 66 mmol) in dimethylsulfoxide (100 ml) was stirred for 43 hours. The solution was treated with water (200 ml) and then extracted with dichloromethane (3×80 ml). The combined extracts were washed with water (3×100 ml), dried over magnesium sulfate, and then the solvent was evaporated under vacuum to give 1-(5-hexenyl)-3,7-dimethylxanthine (17 g, 98% yield) as a white powder.
