(4-Hydroxyphenyl)(3-methylphenyl)methanone (307 mg) was dissolved in xylene to prepare a solution. 4-Dimethylaminopyridine (194 mg) and 4-chloro-6,7-dimethoxyquinoline (342 mg) were added to the solution, and the mixture was heated under reflux for 23 hr. A saturated aqueous sodium hydrogencarbonate solution was added thereto, and the mixture was extracted with chloroform. The organic layer 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, chloroform, and hexane-acetone as solvents to give the title compound (262 mg, yield 45%).
