実験手順

1-(5,6-Oxidohexyl)-3,7-dimethylxanthine was synthesized and used as an intermediate for synthesizing inventive compounds nos. 1517 and 1595 as described in examples 2 and 3 below. A mixture of l-bromo-5-hexene (10.7 g, 66 mmol), sodium hydride (1.58 g, 66 mmol), and 3,7-dimethylxanthine (11.9 g, 66 mmol) in dimethylsulfoxide (100 ml) was stirred for 43 hr. 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.
