Vorschrift

To a mixed solution of sodium iodide (2080 mg, 13876 μmol), indium (2000 mg, 6938 μmol) and 1-bromo-3-methylbut-2-ene (1616 μL, 13876 μmol) in DMF (30 mL), was added T30.3 (1593 mg, 13876 μmol). The mixture was stirred at room temperature for 1 hour, and then was diluted with EtOAc and water. The organic phase was washed with water and brine and then dried over anhydrous sodium sulfate. After filtration, the organic solvent was removed in vacuo to give a residue which was purified by chromatography to give the product as an oil (2.30 g, 92%). MS ESI m/e: 376.1 (M+18)+.
