Methyl iodide → HCID 60026352、化合物

To a solution of 2-methyl-2-phenylpent-4-en-1-ol (3.2 g, 18.15 mmol) in 17 mL of DMF was added sodium hydride (1.25 g, 31.25 mmol, 60% in mineral oil). The mixture was stirred until foaming ceased and then methyl iodide (6 mL, 96 mmol) was added. After 2 hours, the mixture was quenched with 50 mL of saturated aqueous ammonium chloride solution and extracted with three 50 mL portions of ethyl acetate. The combined organic layers were washed with 30 mL of saturated aqueous ammonium chloride solution, five 25 mL portions of brine, dried over magnesium sulfate, filtered, and concentrated in vacuo to afford 3.4 g (98.4% yield) of (1-methoxymethyl-1-methylbut-3-enyl)benzene which was used without further purification.
