Versuchsvorschrift

259 mg (0.39 mmol) of ethyl 5-{(5-ethoxy-5-oxopentyl)[2-(2-{[4-(2-phenylethyl)benzyl]oxy}-phenyl)ethyl]amino}-5,6,7,8-tetrahydroquinoline-2-carboxylate (Enantiomer 1, Example 50A) were taken up in 4 ml of dioxane, 2 ml of a 2 M solution of potassium hydroxide in water were added and the mixture was stirred at room temperature overnight. After the reaction had gone to completio, the reaction mixture was acidified slightly using 0.75 ml of acetic acid and 1 N of hydrochloric acid and then concentrated to dryness. The residue obtained was purified by preparative HPLC. This gave 183 mg (0.30 mmol, 77% of theory) of the title compound.
