Reaction Steps

A solution of 3-butenyl methacrylate (5.1 g) was added slowly to the stirred solution of m-CPBA (10.2) in methylene dichloride (70 ml). The resulting solution was stirred at room temperature for 5 hours and then was washed repeatedly with a dilute aqueous solution of potassium carbonate. The solution obtained was then dried with anhydrous magnesium sulfate and evaporated. Pure 3,4-epoxybutyl methacrylate was isolated by column chromatography on silica gel. Yield 3.9 g.
