Reaction Steps

To a solution of 914 mg (4.54 mmol) of 1-(2'-hydroxy-3'-methoxypropyl)-2-nitroimidazole in 5.0 ml of dry dioxane, 1.00 g (6.20 mmol) of DAST was dropwise added with cooling by ice and then reacted for 2 hours at room temperature with stirring. After reaction, to the solution, 5.0 ml of ethanol was added to decompose excess DAST. The solution was then concentrated and subjected to isolation and purification by silica gel column chromatography to give 480 mg of 1-(2-'-fluoro-3'-methoxypropyl)-2-nitroimidazole.
