실험 절차

4.17 g (9.09 mmol) of rac-ethyl 5-{(tert-butoxycarbonyl)[2-(5-fluoro-2-hydroxyphenyl)ethyl]-amino}-5,6,7,8-tetrahydroquinoline-2-carboxylate, 3.04 g (10.91 mmol) of 5-chloro-2-[4-(chloromethyl)phenyl]-1,3-benzoxazole and 3.14 g (22.74 mmol) of potassium carbonate in 120 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 5.43 g (7.75 mmol, 85% of theory) of the target compound.
