الإجراء التجريبي

A mixture of 15 g (79 mmol) of 4-bromo-thiophenol (Compound 40), 3.16 g (79 mmol) of powdered sodium hydroxide and 150 ml of acetone was heated at reflux for 15 minutes. The refluxing mixture was then treated dropwise with a solution of 12 g (79 mmol) of 1-bromo-3-methylbutane (Compound 49) in 25 ml of acetone and then refluxed for a further 18 hours. The mixture was allowed to cool and the solvent removed in-vacuo. The residue was taken up in 25 ml of water and the mixture basified with 2N NaOH solution. The mixture was extracted with ether and the combined ether extracts washed successively with 1N NaOH, water and saturated NaCl and then dried (MgSO4). The solvent was removed in-vacuo and the residue distilled (113-117 degrees C., 0.2 mm) to give the title compound as a colourless oil. PMR (CDCl3): & 0.93 (6H, d, J~6.6 Hz), 1.47-1.58 (2H, m), 1.65-1.80 (1H, m), 2.90 (2H, t, J~7.8 Hz), 7.18 (2H, d, J~8.6 Hz), 7.39 (2H, d, J~8.6 Hz).
