Versuchsvorschrift

A suspension of 51.21 g (116.24 mmol) of ethyl 5-{(tert-butoxycarbonyl)[2-(2-hydroxyphenyl)-ethyl]amino}-5,6,7,8-tetrahydroquinoline-2-carboxylate (Enantiomer 2, Example 69A), 44.70 g (127.86 mmol) of 4-(bromomethyl)-3-chloro-4′-(trifluoromethyl)biphenyl and 40.16 g (290.60 mmol) of potassium carbonate in 1420 ml of acetonitrile was 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 (2.5 kg) (mobile phase: petroleum ether/ethyl acetate 4:1). This gave 79 g (111.39 mmol, 96% of theory) of the target compound.
