実験手順
A mixture of 2-pyrimidinebutanol (1.31 g), 1,6-dibromohexane (5 ml), 50% aqueous sodium hydroxide solution (5 ml) and TAB (140 mg) was vigorously stirred under nitrogen at 23° for 20 h. Ether (25 ml) and water (20 ml) were added, the organic phase separated, washed with brine (20 ml), dried and evaporated in vacuo. The residue was purified by FCC. Elution with hexane and hexane-ether (9:1) followed by ether afforded the title compound as a colourless oil (1.67 g)
