Vorschrift

The obtained 4-({[5-(9-[{(2R)-[8-(benzyloxy)-2-oxo-1,2-dihydroquinolin-5-yl]-2-hydroxyethyl}amino]nonyl)-2-phenylphenyl]carbamoyl}oxy)-1,1-dimethylpiperidin-1-ium trifluoroacetate was dissolved in methanol (5 mL), 10% palladium-carbon (50 mg) was added thereto, and the mixture was stirred under a hydrogen atmosphere at room temperature for 2 hours. The reaction solution was filtered through celite and the filtrate was concentrated under reduced pressure. The residue was purified by HPLC fractionation to obtain 4-({[5-(9-{[(2R)-2-hydroxy-2-(8-hydroxy-2-oxo-1,2-dihydroquinolin-5-yl)ethyl]amino}nonyl)-2-phenylphenyl]carbamoyl}oxy)-1,1-dimethylpiperidin-1-ium trifluoroacetate (12.79 mg).
