In a 5000 ml flask equipped with a stirrer and a condenser were charged 400.2 g of hydroquinone monobenzyl ether, 586.5 g of ethyl 11-bromoundecanoate, 331.7 g of anhydrous potassium carbonate, 33.2 g of potassium iodide and 1500 ml of N,N-dimethylformamide (DMF), and the mixture was refluxed for 6 hours. This solution was poured into 2000 ml of ice-water to precipitate white crystals. The precipitated crystals were collected by filtration, washed with distilled water and recrystallized from ethanol to obtain 535.5 g of the title compound.
