2-Isopropenyl-6-methoxy-2,3-dihydrobenzofuran, prepared from m-methoxyphenol and 1,4-dibromo 2-methyl-2-butene, was converted to racemic dihydroageratone via oxidation with selenium dioxide, the acetylation with acetic acid–trifluoroacetic anhydride, and the demethylation with magnesium iodide etherate.
