実験手順

Manganese dioxide (14.7 g) was added at room temperature to a toluene (80 mL) solution of (4,5-dicyclopropyl-2-isopropoxyphenyl)methanol (5.22 g), and the mixture was stirred at 80° C. for 1 hour in a nitrogen atmosphere. The reaction mixture was filtered through celite, and then, the filtrate was concentrated. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate) to obtain the title compound (4.88 g).
