Reaction Conditions

Reaction Steps

Manganese dioxide (10.8 g) was added to a toluene (30 mL) solution of (2-cyclopropyl-2′,4′-difluoro-5-isopropoxybiphenyl-4-yl)methanol (3.97 g), and the mixture was stirred at 60° C. for 1 hour in a nitrogen atmosphere. The reaction mixture was filtered, and then, the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate) to obtain the title compound (3.53 g).
