Abstract
The formation of ester derivatives of alcohols for the purpose of HPLC-ultraviolet/fluorescence analysis is achieved rapidly when a mixture of the alcohol and the triethylamine salt of the required acid in chloroform or dichloromethane is treated with a solution of either 2,4,6-triisopropylbenzenesulphonyl chloride or 2,4,6-trimethylbenzenesulphonyl chloride (mesitylenesulphonyl chloride) followed by 4-dimethylaminopyridine in the same solvent. Aromatic carboxylic acids give a quantitative yield of the esters while the yield is reduced for arylacetic acids.
