実験手順

To a solution of 4-iodo-1-methylimidazole (0.424 g, 2.04 mmol) in CH2Cl2 at rt was added EtMgBr (3.0 M in Et2O, 0.75 mL, 2.25 mmol) and the resulting solution was allowed to stir for 30 min at rt. To this solution was then added Bu3SnCl (0.60 mL, 2.21 mmol) and the mixture was stirred for another 7 h. The resulting mixture was then washed (sat. NH4Cl, H2O, brine), dried (Na2SO4) and evaporated to give the title compound, which was used directly in the following step without further purification:
