Procedure

To a stirred solution of 146 g of [4-[2-(5-cyano-2-hydroxybenzenesulfonylamino)ethyl]-2′-methanesulfonyl-biphenyl-3-yloxy]acetic acid in 580 mL of ethanol was added 137 mL of 2mol/L sodium hydroxide solution under ice-cooling, and the solvent was removed under reduced pressure. The residue was suspended with 1.16 L of ethanol, and the mixture was stirred under reflux for an hour, then at room temperature overnight. The obtained white solid was collected by filtration to give 129 g of sodium[4-[2-(5-cyano-2-hydroxybenzenesulfonyl-amino)ethyl]-2′-methanesulfonylbiphenyl-3-yloxy]acetate.
