557 ml of a 4 N solution of hydrogen chloride in dioxane, diluted with a further 389 ml of dioxane, were added to 79 g (111.39 mmol) of ethyl 5-{(tert-butoxycarbonyl)[2-(2-{[3-chloro-4′-(trifluoromethyl)biphenyl-4-yl]methoxy}phenyl)ethyl]amino}-5,6,7,8-tetrahydroquinoline-2-carboxylate (Enantiomer 2, Example 74A), and the mixture was stirred at room temperature overnight. The reaction solution was then concentrated to dryness and the residue was dried under high vacuum overnight. This gave 78 g (111.39 mmol, about 100% of theory) of the target product.
