Scandium trifluoromethanesulfonate (49 mg) was added to the solution, and the mixture was stirred at 60° C. overnight. A saturated aqueous sodium hydrogencarbonate solution was added thereto, and the mixture was extracted with chloroform. The organic layer was washed with saturated brine, was dried over sodium sulfate, and was then concentrated. The residue was subjected to separation and purification by column chromatography on silica gel using hexane-acetone as a solvent to give (4-methoxyphenyl)(3-methylphenyl)methanone (633 mg, yield 56%).
