Reaction Conditions

Reaction Steps

To a solution of 3′-(hydroxymethyl)-2,6-dimethylbiphenyl-4-ol (1.83 g, 8.00 mmol) and 2-chloroethyl ethyl sulfide (1.07 mL, 12.0 mmol) in N,N-dimethylformamide (15 mL) were added potassium carbonate (1.33 g, 9.60 mmol) and potassium iodide (0.132 g, 0.800 mmol), and the mixture was stirred at 95° C. for 24 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=10:90-50:50) to give the title compound (1.19 g, yield 47%) as a colorless oil.
