반응 단계

4-Phenoxy-1-butanol (4 g), 1,6-dibromohexane (6.7 ml), TAB (0.8 g) and sodium hydroxide (9.4 g in 18 ml water) were stirred at room temperature under nitrogen for 20 h. Water (80 ml) was added and the mixture extracted with diethyl ether (3×100 ml). The combined organic extracts were washed with water (50 ml), brine (50 ml), dried and evaporated to give a colourless liquid. This was applied to an FCC column and eluted with cyclohexane (2 l) and then with System A (1:40). The resulting oil was distilled to give the title compound (3.4 g) as a colourless oil b.p. 150°/3.5 mmHg T.l.c. (System A 1:6) Rf 0.3.
