Participants

Reaction Steps

2.26 g of {[5-(1-hydroxy-1-methylethyl)-isoxazol-3-yl]methylidene}malononitrile was dissolved in 50 ml of 1,4-dioxane. Thereto, 0.08 g of copper(I) iodide was added and 18.6 ml of a 1.4 M solution of allylmagnesium chloride in tetrahydrofuran was then added under ice-cooling. The mixture was stirred for 1 hour under ice-cooling. The reaction mixture was added to 0.1 M hydrochloric acid and then extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, filtered and then concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to obtain 0.56 g of {1-[5-(1-hydroxy-1-methylethyl)-isoxazol-3-yl]allyl}malononitrile.
