Reaktionsschritte
A solution of 4-hydroxybenzoic acid (3 g), decanoic acid chloride (4.3 g), triethylamine (2.4 g) and dimethylaminopyridine (0.2 g) in methylene chloride (50 ml) was stirred at room temperature for 24 hours, and then poured in water. The solution was neutralized with dilute aqueous hydrochloric acid solution and extracted with dimethyl ether. The extracted product was dried over anhydrous magnesium sulfate and distilled to remove the solvent. The residue was washed enough with hexane to obtain the titled compound (2.7 g).
