Reaction Steps

To a solution of the compound obtained in the (1) (8.22 g) in 1,4-dioxane 9100 mL) were added potassium carbonate (8.6 g), trimethylboroxine (3.5 mL) and 1,1′-bis(diphenylphosphino)ferrocene dichloropalladium (II) (1.51 g), and the mixture was heated to stir at 110° C. for 2 hours. After cooling to room temperature, thereto was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated saline, dried over sodium sulfate, and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent: n-hexane→n-hexane/ethyl acetate=5/1) to give 1-[3-(3-methoxypropoxy)-5-methylphenyl]ethanone [REx(21-2)] (4.15 g) as a brown oil.
