実験手順

To a solution of 3′-(hydroxymethyl)-2,3,5,6-tetramethylbiphenyl-4-ol (0.616 g, 2.40 mmol) and 3-(methylsulfonyl)propyl 4-methylbenzenesulfonate (1.05 g, 3.60 mmol) in N,N-dimethylformamide (5 mL) was added potassium carbonate (0.597 g, 4.32 mmol), and the mixture was stirred at 90° C. for 12 hr under nitrogen atmosphere. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed successively with 1 M aqueous sodium hydroxide solution and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=40:60-80:20), and the obtained crystals were recrystallized from heptane-ethyl acetate to give the title compound (0.577 g, yield 85%) as colorless crystals.
