Procedure

479 mg (0.64 mmol) of rac-ethyl 5-[(2-{5-fluoro-2-[(4-{2-[4-(trifluoromethyl)phenyl]ethyl}-benzyl)oxy]phenyl}ethyl)amino]-5,6,7,8-tetrahydroquinoline-2-carboxylate dihydrochloride (Example 158A) were taken up in 4.7 ml of THF, 0.27 ml of triethylamine was added and the mixture was stirred at room temperature for one hour. Ethyl acetate and water were then added to the reaction solution, the phases were separated and the aqueous phase was extracted once more with ethyl acetate. The combined organic phases were again washed with water, dried over magnesium sulphate, filtered and then concentrated to dryness. This gave 383 mg (0.62 mmol, 96% of theory) of the target compound.
