Versuchsvorschrift
13.9 g of p-n-decyloxybenzoic acid was heated with excess thionyl chloride for 1 hour under reflux. p-n-Decyloxybenzoic acid chloride was obtained after distilling unreacted thionyl chloride off. 10.6 g of the above prepared p-hydroxybenzoic acid 2-methylbutyl ester was dissolved in 40 ml of pyridine. When the solution was cooled, a toluene solution of said p-n-decyloxybenzoic acid chloride was admixed therewith under stirring to effect reaction at 80° C. for 2 hours. The solution was then acidified by the addition of ice and 6N hydrochloric acid. After the organic layers were washed with water, then with a 2N aqueous sodium hydroxide solution, and again with water, the solvent was distilled off. The residue was recrystallized twice from ethanol to obtain p-n-decyloxybenzoic acid p'-(2-methylbutoxycarbonyl)phenyl ester.
