Procedure

To a solution of 290 mg of ethyl[4-[2-(5-carbamimidoyl-2-hydroxybenzenesulfonylamino)ethyl]-2′-methanesulfonoylbiphenyl-3-yloxy]acetate in 1.0 mL of acetonitrile was added 0.756 mL of 2 mol/L sodium hydroxide solution, and the mixture was stirred at room temperature for 30 minutes. To the reaction mixture was added 1.26 mL of 2 mol/L hydrochloric acid, and the mixture was concentrated under reduced pressure. To the residue was added water, and the mixture was purified by column chromatography on trimethylaminopropylated silica gel (eluent: 10% 1 mol/L hydrochloric acid-acetonitrile). The eluent was concentrated under reduced pressure to give 260 mg of [4-[2-(5-carbamimidoyl-2-hydroxybenzenesulfonylamino)ethyl]-2′-methanesulfonoylbiphenyl-3-yloxy]acetic acid hydrochloride as a white solid.
