A mixture of 2-thiophenepropanol (5 g), 1,6-dibromohexane (25 g), 50% aqueous sodium hydroxide (25 ml) and TAB (500 mg) was stirred at room temperature overnight. Water (100 ml) was added and the mixture was extracted with ether (2×100 ml). The organic layer was dried and concentrated to an oil which was purified by FCC eluting with hexane to give the title compound as a colourless oil (6.6 g). T.l.c. (hexane-diethyl ether 9:1) Rf 0.50.
