98 mg (0.13 mmol) of ethyl 5-[{2-[4-(methoxycarbonyl)phenyl]ethyl}(2-{2-[(4-{2-[4-(trifluoromethyl)phenyl]ethyl}benzyl)oxy]phenyl}ethyl)amino]-5,6,7,8-tetrahydroquinoline-2-carboxylate (Enantiomer 2, Example 156A) were dissolved in 2.5 ml of dioxane, 0.4 ml of 1 N aqueous sodium hydroxide solution was added and the mixture was then stirred at room temperature overnight. After the reaction had gone to completion, the dioxane was removed on a rotary evaporator and the mixture that remained was diluted with water. The mixture was then acidified with acetic acid to pH 4-5. The precipitated solid was filtered off with suction, washed repeatedly with water and then dried in a drying cabinet under reduced pressure at 40° C. for three days. This gave 71 mg (73% of theory) of the title compound.
