Water → 3-Iodoquinoline

Participants

Reaction Steps

3-Bromoquinoline (64.00 g, 308 mmol), N,N′-dimethylethylenediamine (13.5 ml, 127 mmol), cuprous iodide (12.00 g, 63.0 mmol) and sodium iodide (112 g, 747 mmol) in dioxane (300 ml) was placed into a preheated oil bath at 100° C. After stirring for 18 h, the heterogeneous mixture was diluted water and extracted with methylene chloride. The combined organic extracts were dried over magnesium sulfate, filtered, and concentrated under reduced pressure. The residue was flash chromatographed with methylene chloride as the eluant to afford 68.47 g (87% yield) of 3-iodoquinoline as a yellow solid. Method [8] retention time 6.47 min by HPLC (M+=256).
