Procedure
The resulting 5-octanoyl-2,2-dimethyl-1,3-dioxane-4,6-dione was allowed to reflux in ethanol for 2 hours, and then concentrated under reduced pressure. The resulting residue was purified using silica gel chromatography (developing solvent: n-hexane/ethyl acetate=8/2) to obtain ethyl 3-oxodecanoate shown by the formula below.
