Procedure

To a mixture of 230 mg of methyl 4-(3-{4-[({2-[(3-{ethyl[trans-4-(methoxycarbonyl)cyclohexyl]sulfamoyl}benzoyl)amino]-4,5,6,7-tetrahydro-1-benzothiophen-3-yl}carbonyl)amino]phenyl}propyl)benzoate, 2 mL of methanol, and 2 mL of THF was added 2 mL of a 1 M aqueous NaOH solution, followed by stirring at 60° C. for 2 days. The reaction mixture was cooled and then concentrated under reduced pressure. The obtained residue was diluted with water and then neutralized with 1 M hydrochloric acid. To the reaction mixture was added 0.5 mL of THF and the precipitate was collected by filtration. The obtained solid was suspended in 10 mL of ethanol, and then the precipitate was collected by filtration to obtain 147 mg of 4-{3-[4-({[2-({3-[(trans-4-carboxycyclohexyl)(ethyl)sulfamoyl]benzoyl}amino)-4,5,6,7-tetrahydro-1-benzothiophen-3-yl]carbonyl}amino)phenyl]propyl}benzoic acid as a beige crystal.
