Reaction Steps

5.2 ml of a 4 N solution of hydrogen chloride in dioxane were added to 500 mg (0.69 mmol) of rac-ethyl 5-[(tert-butoxycarbonyl)(2-{5-fluoro-2-[(4-{2-[4-(trifluoromethyl)phenyl]-ethyl}benzyl)oxy]phenyl}ethyl)amino]-5,6,7,8-tetrahydroquinoline-2-carboxylate (Example 157A), and the mixture was stirred at room temperature for 2 h. The reaction mixture was then concentrated to dryness. This gave 479 mg of the target product which was reacted further without further analytical characterization.
