Reaction Steps

To a solution of 3.93 g (17.1 mmol) of 1-(2'-hydroxy-3'-acetoxypropyl)-2-nitroimidazole in 30 ml of dry dioxane, 4.00 g of DAST was dropwise added with stirring and cooling by ice. After addition, the mixture was reacted for 5 hours at room temperature with stirring. Thereafter, to the solution, 10 ml of ethanol was added to decompose excess DAST. The solution was then concentrated and partitioned between chloroform and an aqueous solution of sodium hydrogen carbonate. The chloroform phase was dried on magnesium sulfate and filtered. The filtrate was concentrated and subjected to isolation and purification by silica gel column chromatography to give 1.15 g of 1-(2'-fluoro-3'-acetoxypropyl)-2-nitroimidazole.
