Procedure

112 mg (0.39 mmol) of methyl 4-(2-iodoethyl)benzoate and 41 mg (0.39 mmol) of anhydrous sodium carbonate were added to a solution of 149 mg (0.26 mmol) of ethyl 5-{[2-(2-{[4-(5-chloro-1,3-benzoxazol-2-yl)benzyl]oxy}phenyl)ethyl]amino}-5,6,7,8-tetrahydroquinoline-2-carboxylate (Enantiomer 1, Example 61A) in 10 ml of dry acetonitrile, and the mixture was heated under reflux overnight. A further 112 mg of methyl 4-(2-iodoethyl)benzoate were then added, and the mixture was once more heated under reflux overnight. The reaction was then evaporated to dryness, the residue was taken up in water and ethyl acetate and the phases were separated. The organic phase was evaporated to dryness and the residue obtained was purified by preparative HPLC. This gave 72 mg (0.10 mmol, 38% of theory) of the title compound.
