An amount of 76.2 g (0.15 mol) of 2-[m-(3-chloro-2,2,3-trifluoropropionamido)-phenoxy]-myristic acid ethyl ester is dissolved in a mixture of 300 ml of acetic acid and 37.5 ml of 40% aqueous hydrobromic acid. The reaction mixture is heated for 15 min at 100° C., next poured out in 500 ml of methylene chloride, and finally extracted with methylene chloride. The extract is rinsed with water until neutral, dried over magnesium sulphate, and heated to remove any remaining solvent by evaporation.
