Reaction Steps

23 ml of a 4 N solution of hydrogen chloride in dioxane were added to 6080 mg (9.06 mmol) of ethyl 5-[(tert-butoxycarbonyl){2-[5-fluoro-2-({4-[2-(4-fluorophenyl)ethyl]benzyl}oxy)phenyl]-ethyl}amino]-5,6,7,8-tetrahydroquinoline-2-carboxylate (Enantiomer 2, Example 140A), and the mixture was stirred at room temperature for 2 h. The reaction mixture was then concentrated to dryness. This gave 6240 mg of the target product which was reacted further without further analytical characterization.
