Versuchsvorschrift

In methanol (50 ml) was dissolved methyl 1-(N-acetylglycyl)-7-[4-(2-butoxyethoxy)phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxylate (1.2 g). To the solution was added 1N sodium hydroxide solution (13 ml), and the mixture was stirred at room temperature overnight, concentrated, neutralized with 1N hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with water and saturated brine and dried with anhydrous magnesium sulfate. The solvent was evaporated to give 1-(N-acetylglycyl)-7-[4-(2-butoxyethoxy)phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxylic acid (1.2 g) as colorless crystals.
