실험 절차

A mixture of sodium hydride (343 mg, 14 mmol) and 1-methylthymine (2.00 g, 14 mmol) in dimethylsulfoxide (30 ml) was stirred for 15 minutes, and then 6-bromo-1-hexene (2.30 g, 14 mmol) was added. After stirring for 69 hours, the reaction mixture was poured into water (100 ml) and extracted with dichloromethane (4×50 ml). The combined organic layers were washed with saturated aqueous sodium chloride solution (40 ml), dried over sodium sulfate, and then the solvent was evaporated under vacuum to give a residue which was recrystallized (dichloromethane-ethyl ether) to give 3-(5-hexenyl)-1-methylthymine (2.80 g, 88% yield).
