Reaction Steps

12 ml of a 4 N solution of hydrogen chloride in dioxane were added to 1100 mg (1.57 mmol) of ethyl 5-[(tert-butoxycarbonyl)(2-{2-[(4-{2-[4-(trifluoromethyl)phenyl]ethyl}benzyl)oxy]phenyl}-ethyl)amino]-5,6,7,8-tetrahydroquinoline-2-carboxylate (Enantiomer 2, Example 153A), and the mixture was stirred at room temperature for 2 h. The reaction mixture was then concentrated to dryness. This gave 1045 mg of the target product which was reacted further without further analytical characterization.
