Reaction Steps

To a suspension of ethyl 4-(5-chloro-2-{[(2-{1-[4-hydroxy-1-methyl-5-(4-trifluoromethylphenyl)-1H-pyrazol-3-yl]ethylidene}hydrazino)carbonothioyl]amino}-phenoxy)butyrate (74 mg, 0.12 mmol) in ethanol (3.0 mL) was added 1 M aqueous sodium hydroxide (370 μL, 0.37 mmol). After the reaction mixture was stirred at room temperature for 19 hours, 1 M hydrochloric acid (370 μL, 0.37 mmol) was added then the precipitated solid was collected by filtration, washed with chloroform and dried by means of a vacuum pump to give the desired product as a yellow solid (yield 59%).
