Procedure
A mixture of 1-(4-carboxyphenyl)-5-[4-(methylsulfonyl)phenyl]-3-(trifluoromethyl)pyrazole (2.2 g) and hydrogen chloride in ethanol (50 ml) was refluxed for 6 hours. The solvent was evaporated and the residue was recrystallized from ethanol to give crystals of 1-[4-(ethoxycarbonyl)phenyl]-5-[4-(methylsulfonyl)phenyl]-3-(trifluoromethyl)pyrazole (2.3 g).
