Procedure

660 mg (1.20 mmol) of ethyl 3-{3-[3,5-bis(trifluoromethyl)phenyl]-2-oxoimidazolidin-1-yl}-1-(3-chloropyridin-2-yl)-1H-pyrazole-5-carboxylate were dissolved in 10 ml of ethanol, 72 mg (1.80 mmol) of 2N aqueous sodium hydroxide solution were added and the mixture was stirred at RT for 1 h. The solvent was distilled off under reduced pressure, the residue was taken up in water and the mixture was extracted once with methyl tert-butyl ether. The aqueous phase was then acidified with 2N hydrochloric acid and extracted three times with ethyl acetate. The combined organic phases were dried over sodium sulphate and concentrated.
