Procedure

A mixture of 230 mg of methyl 4-{2-[4-({[2-({3-[(2,3-dihydroxypropyl)(methyl)sulfamoyl]benzoyl}amino)-4,5,6,7-tetrahydro-1-benzothiophen-3-yl]carbonyl}amino)phenyl]ethyl}benzoate, 1.5 mL of a 1.0 M aqueous sodium hydroxide solution, and 2.3 mL of ethanol was heated and refluxed overnight. The reaction mixture was concentrated under reduced pressure, and to the residue were added water, citric acid, and dichloromethane in this order. The organic layer was separated and concentrated under reduced pressure. The obtained residue was solidified with THF-hexane to obtain 180 mg of 4-{2-[4-({[2-({3-[(2,3-dihydroxypropyl)(methyl)sulfamoyl]benzoyl}amino)-4,5,6,7-tetrahydro-1-benzothiophen-3-yl]carbonyl}amino)phenyl]ethyl}benzoic acid as a colorless solid.
