In a pressure tube with one end sealed, add 190 mg CuI (1 mmol), 1.64 g 4-methyl-1H-imidazole (20 mmol), 3.25 g Cs2CO3 (10 mmol), and after Nitrogen replacement, add 2.40 g 3-bromo-5-(trifluoromethyl)aniline (10 mmol), 350 mg 1-(5,6,7,8-tetrahydroquinolin-8-yl)ethanone (2 mmol) and 30 mL DMF was added into a flask. The mixture was stirred at 110° C. for 18 h under sealing. After cooling to room temperature, the solvent was removed under vacuum and the residue was purified by column chromatography to afford 2.19 g desired product (91%).
