To a solution of 5-[(4-hydroxyphenyl)methyl]-2,4-thiazolidinedione (0.30 g, 1.3 mmol) in dimethyl sulfoxide (20 mL) were added 3-(chloromethyl)biphenyl (0.26 g, 1.3 mmol) and 60% sodium hydride (0.11 g, 2.6 mmol), and the mixture was stirred at room temperature for 1 hr and further at 50° C. for 1 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with water and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=8:2) to give the title compound (1.3 g, yield 96%).
