A mixture of 2-[(2-phenylethyl)thio]ethanol (1.0 g), 1,4-dibromobutane (3.79 g), TAB (0.6 g) and 50% aqueous sodium hydroxide (12 ml) was stirred at room temperature under nitrogen for 20 h. The mixture was diluted with water (100 ml), extracted with diethyl ether (2×100 ml), dried and evaporated in vacuo to give an oil. Purification by FCC eluting with cyclohexane followed by System B (5:95) gave the title compound (1.34 g) as a colourless oil. T.l.c. (System F 3:1) Rf 0.62.
