Example 37 This example illustrates the synthesis of 1-(8-Nonenyl)-3,7-dimethylxanthine (CT1550). A mixture of theobromine (17.64 g, 98 mmol) and sodium hydride (2.35 g, 98 mmol) in dimethylsulfoxide (250 ml) was stirred for 15 min. After addition of 9-bromo-1-nonene (Alfebro, 20.0 g, 98 mmol) stirring was continued at ambient temperature for 3 days. The reaction mixture was then poured into water (300 ml) and extracted with dichloromethane (4*200 ml). The combined organic layers were washed with saturated aqueous salt solution (2*150 ml) and dried over sodium sulfate. The solvent was evaporated under vacuum to give a thick oil. After cooling a solution of the oil in a minimum of dichloromethane and ether, 1-(8-nonenyl)-3,7-dimethylxanthine (CT1550) (24.34 g, 77.5 mmol, 99% yield) formed as white crystals.
The synthetic route of 89359-54-6 has been constantly updated, and we look forward to future research findings.
