실험 절차

A mixture of 875 mg of sodium hydride (as a 55% w/w dispersion in mineral oil) in 5 ml of dimethyl sulfoxide was stirred at room temperature for 30 minutes in an atmosphere of nitrogen, and then a solution of 2.42 g (10 mmol) of thymidine in 5 ml of dimethyl sulfoxide was added dropwise to the resulting mixture. The mixture was stirred at room temperature for 30 minutes, after which a suspension of 2.51 g (10 mmol) of 1-(chloromethyl)pyrene [Acta Chem. Scand., 10, 1362 (1936)] in 15 ml of dimethyl sulfoxide was added. The mixture was then stirred at room temperature for 90 minutes. At the end of this time, the reaction mixture was poured into 100 ml of ice-water, and the aqueous mixture was extracted with 100 ml of ethyl acetate and then with 100 ml of methylene chloride. The extract was dried over anhydrous magnesium sulfate, and then the solvent was removed by distillation under reduced pressure. The residue was purified by column chromatography through 150 g of silica gel (230-400 mesh), using a gradient elution method, with mixtures of methylene chloride containing from 0 to 4% by volume of methanol as the eluent, to give 292.4 mg (yield 6.4%) of the title compound.
