Reaction Steps

By customary procedures, 3.5 g of benzyl 4-undecylcarboxybenzoate was prepared from 2.3 g of benzyl 4-hydroxybenzoate and 2.5 g of lauric acid chloride, and this ester was catalytically reduced under a hydrogen pressure of 2 kg/cm2 by using Pd/C as the catalyst to obtain 2.8 g of 4-undecylcarboxybenzoic acid. The acid was converted to 4-undecylcarboxybenzoic acid chloride by thionyl chloride and the acid chloride was reacted with 1.8 g of benzyl 4-hydroxybenzoate to form benzyl 4-(4-undecylcarboxybenzoyloxy)benzoate. The ester was catalytically reduced under a hydrogen pressure of 2 kg/cm2 by using Pd/C as the catalyst to isolate the benzyl group and obtain 3.0 g of 4-(4'undecylcarboxybenzoyloxy)benzoic acid.
