실험 절차

A 100-ml eggplant type flask was charged with 6.9 g (50 mmol) of 2,5-dimethylthiophenol, 5.5 g (60 mmol, 1.2 equivalents) of methallyl chloride which was a halogenated olefin, 6.9 g (50 mmol, 1 equivalent) of potassium carbonate and 30 ml of acetone, and the mixture was refluxed under heat for 1 hour. The reaction mixture was allowed to cool, insolubles were removed by filtration, and the acetone was distilled off. The resultant residue was re-dispersed in n-hexane and washed with a saturated sodium chloride aqueous solution. An organic layer was dried over anhydrous sodium sulfate, and then the solvent was distilled off to give 8.6 g (yield 89%) of 2-methyl-3-(2,5-dimethylphenylthio)-propane.
