実験手順

2 g (7 mmol) of ethyl 3-(2-bromoethoxy)-2-methylbenzoate and 1.1 g (7.3 mmol) of potassium thiomethanesulfonate are dissolved in 10 ml of abs. ethanol. The reaction mixture is refluxed for 20 hours. The solvent is then distilled off and the residue is taken up in methylene chloride and washed with water. The organic phase is dried over sodium sulfate and the solvent is removed. The useful product is purified by column chromatography.
