Versuchsvorschrift

A mixture of 300 mg of methyl 4-{2-[4-({[2-({3-[(4-acetylpiperazin-1-yl)sulfonyl]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 3.0 mL of ethanol was heated and refluxed overnight. The reaction mixture was concentrated under reduced pressure and the residue was neutralized with 1.0 M hydrochloric acid. Then, the precipitate was collected by filtration and the obtained solid was purified by silica gel column chromatography (methanol-chloroform) to obtain 116 mg of 4-{2-[4-({[2-({3-[(4-acetylpiperazin-1-yl)sulfonyl]benzoyl}amino)-4,5,6,7-tetrahydro-1-benzothiophen-3-yl]carbonyl}amino)phenyl]ethyl}benzoic acid as a colorless crystal.
