Reaktionsschritte
In ethanol, chlorohydroquinone was reacted with dodecylbromide in ethanol by using 1 equivalent of potassium hydroxide to obtain 3-chloro-4-dodecyloxyphenol. Then, 3.1 g of this 3-chloro-4-dodecyloxyphenol was reacted with 2.0 g of 2,4-acetoxybenzoic acid chloride in pyridine and the reaction mixture was treated by customary procedures to obtain 4 g of 3-chloro-4-dodecyloxyphenyl 4-acetoxybenzoate. This ester was dissolved in a THF/methanol liquid mixture and 1 equivalent of 1N LiOH was added to selectively isolate the acetoxy group, whereby 3-chloro-4-dodecyloxyphenyl 4-hydroxybenzoate was obtained.
