Reaction Steps

In 1 L DMF, sodiul hydride (8.7 g, 0.36 mole, 1 eq.) was added under N2 at room temperature. Then sesamol (50 g, 0.36 mole) was added portionwise to the reaction mixture and stirred 20 minutes at room temperature. Ethyl 2-chloroacetoacetate (59.6 g, 1 eq.) was added slowly and the mixture was heated to 100° C. using an oil bath for 3 hours. The reaction mixture was poured into water and extracted with ethyl acetate, dried over magnesium sulfate and evaporated. The residue was flash chromatographed using hexane ethyl acetate 10%, to give: 50 g (52% yield) of ethyl 2-(3,4-methylenedioxyphenoxy)acetoacetate.
