Versuchsvorschrift

1 g (2.27 mmol) of ethyl 5-{(tert-butoxycarbonyl)[2-(2-hydroxyphenyl)ethyl]amino}-5,6,7,8-tetrahydroquinoline-2-carboxylate (Enantiomer 2, Example 69A), 746 mg (2.50 mmol) of 1-(chloromethyl)-4-{2-[4-(trifluoromethyl)phenyl]ethyl}benzene and 784 mg (5.68 mmol) of potassium carbonate in 25 ml of acetonitrile were heated to 110° C. and stirred at this temperature overnight. After cooling, the reaction mixture was filtered, the filter cake was washed repeatedly with acetonitrile and the combined filtrates were concentrated to dryness on a rotary evaporator. The residue obtained was purified chromatographically on silica gel (mobile phase: cyclohexane/ethyl acetate 20:1→10:1). This gave 1110 mg (1.48 mmol, 65% of theory) of the target compound.
