Procedure

2 g (4.36 mmol) of rac-ethyl 5-{(tert-butoxycarbonyl)[2-(5-fluoro-2-hydroxyphenyl)ethyl]amino}-5,6,7,8-tetrahydroquinoline-2-carboxylate (Example 106A), 1433 mg (4.80 mmol) of 1-(chloromethyl)-4-{2-[4-(trifluoromethyl)phenyl]ethyl}benzene and 1507 mg (10.90 mmol) of potassium carbonate in 50 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 2490 mg (3.29 mmol, 95% of theory) of the target compound.
