2.80 g (6.43 mmol) of ethyl 4,4,4-trifluoro-3-methyl-2-(4-{[2-oxo-5-(trifluoromethyl)pyridin-1(2H)-yl]methyl}phenyl)butanoate were dissolved in 18.2 ml each of THF, methanol and water, and 51.5 ml (128.6 mmol) of 10% strength aqueous sodium hydroxide solution were added. The mixture was stirred at RT overnight. The reaction mixture was then diluted with water, acidified with 1 N hydrochloric acid and extracted with ethyl acetate. The organic phase was dried over sodium sulfate and concentrated. This gave 2.82 g of product, which was used without further purification.
