반응 단계

Theobromine (11.9 g, 66 mmol, available from Sigma) was added to a mixture of bromohexene (10.7 g, 66 mmol, available from Aldrich) and sodium hydride (1.58 g, 66 mmol) in dimethylsulfoxide (100 ml) and the resulting mixture stirred for 43 hours. The solution was treated with water (200 ml) and then extracted with three 80 ml aliquots of dichloromethane. The combined extracts were washed with three 100 ml aliquots of water and dried over magnesium sulfate. The solvent was evaporated under vacuum, leaving 17 g of a white powder, 1-(5-hexenyl)-3,7-dimethylxanthine (65 mmol, 98% yield).
