実験手順

t-Butyl methyl 7-bromoheptylmalonate (8.81 g, 25.1 mmol) is dissolved in acetone (50 ml). Sodium iodide (3.7 g, 25.1 mmol) is added and the mixture is stirred at reflux for 2 hours. The reaction mixture is filtered and the filtrate is concentrated to dryness. The residue is dissolved in methylene chloride and filtered again. The filtrate is concentrated to dryness to give t-butyl methyl 7-iodoheptylmalonate as an oil.
