Reaction Steps

11.1 g of hydroquinone, 3.1 g of 85% KOH and 100 ml of ethanol were mixed and the reaction was carried out for 2.5 hours. 10.7 g of (2'-dodecyloxypropyl) p-toluenesulfonate was added dropwise and after the reaction was carried out at 60° C. for 3 hours and by heating under reflux for 7.0 hours, ethanol was evaporated. The residue was diluted with 200 ml of water, acidified with a small amount of hydrochloric acid and then extracted with 500 ml of hexane, followed by recrystallization. Yield: 1.1 g (12%). Optical rotation [α]D26° =-8.6°.
