Procedure
5.60 g (12.71 mmol) of rac-ethyl 5-{(tert-butoxycarbonyl)[2-(2-hydroxyphenyl)ethyl]amino}-5,6,7,8-tetrahydroquinoline-2-carboxylate, 3.79 g (15.25 mmol) of 1-(chloromethyl)-4-[2-(4-fluorophenyl)ethyl]benzene and 2.64 g (19.07 mmol) of potassium carbonate in 200 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 10:1→4:1). This gave 6.8 g (10.42 mmol, 82% of theory) of the target compound.
