Water → Ethyl 5-({2-[5-fluoro-2-({4-[2-(4-fluorophenyl)ethyl]benzyl}oxy)phenyl]ethyl}amino)-5,6,7,8-tetrahydroquinoline-2-carboxylate

Participants

Reaction Steps

6240 mg (10.28 mmol) of ethyl 5-({2-[5-fluoro-2-({4-[2-(4-fluorophenyl)ethyl]benzyl}-oxy)phenyl]ethyl}amino)-5,6,7,8-tetrahydroquinoline-2-carboxylate dihydrochloride (Enantiomer 2, Example 141A) were taken up in 103 ml of THF, 5.7 ml of triethylamine were 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 finally evaporated to dryness. This gave 3600 mg (6.31 mmol, 61% of theory) of the target compound which was reacted further without further analytical characterization.
