Into a 250-mL 3-necked round-bottom flask, maintained with a nitrogen atmosphere, was placed I2 (10 mg, 0.04 mmol) and Mg (500 mg, 20.83 mmol, 2.07 equiv). Then 1-bromo-2-propylbenzene (2.0 g, 10.05 mmol, 1.00 equiv) dissolved in tetrahydrofuran (50 mL) was added dropwise into the flask and the mixture was heated to reflux. After the reaction was complete the resulting mixture was cooled to 0° C. and then oxirane (50 mL) was added in one portion. The resulting solution was stirred overnight at room temperature. The reaction was then quenched by the addition of 5 mL of NH4Cl (aq.). The solids were filtered out. The filtrate was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:5). Purification afforded 0.24 g (15%) of 2-(2-propylphenyl)ethan-1-ol as a colorless oil.
