実験手順
(4-Methoxyphenyl)(3-methylphenyl)methanone (603 mg) was dissolved in dichloromethane (3 ml) to prepare a solution. A boron tribromide-dichloromethane solution (1.0 M) (11 ml) was added to the solution, and the mixture was stirred at room temperature for 2 days. The reaction solution was poured into ice-cooled water, 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/ethyl acetate as a solvent to give (4-hydroxyphenyl)(3-methylphenyl)methanone (1.50 g, yield 56%).
