1,2-Bis(4-hydroxyphenyl)ethane-1,2-dione (0.77 g, 3.18 mmol) was dissolved in 20 mL of DMF. Potassium carbonate (1.3 g, 9.4 mmol), tetrabutylammonium bromide (0.5 g, 1.55 mmol) and 1-bromo-2-methylpropane (0.86 mL, 7.91 mmol) were added, then the reaction was stirred at 130° C. overnight. The mixture was extracted with ethyl acetate and the organic phase was washed with water, dried over sodium sulfate. Concentration under vacuum gave the title compound as oil (1.2 g, quantitative).
