Vorschrift

Ethyl (3-[(4-methoxybenzoyl)amino]-2-{[4-(4-methyl-1,4-diazepan-1-yl)benzoyl]amino}phenoxy)acetate hydrochloride (350 mg) was dissolved in 6 ml of methanol, then 1.8 ml of a 1N aqueous solution of sodium hydroxide was added at room temperature and the mixture was stirred for 2 hours. 1N hydrochloric acid (1.8 ml) was further added and the mixture was concentrated in vacuo. The resulting residue was purified by ODS column chromatography using 0.001N hydrochloric acid-acetonitrile (1:1) as an eluting solvent to give 254 mg of (3-[(4-methoxybenzoyl)amino]-2-{[4-(4-methyl-1,4-diazepan-1-yl)benzoyl]amino}phenoxy)acetic acid hydrochloride.
