実験手順

To a solution of 5.0 ethyl 4,6-dichloroquinoline-3-carboxylate (1.08 g, 4 mmol, lequiv.) in 1,4-dioxane (10 mL) at room temperature was added compound 5.1 1-(4-(4-amino-2-(trifluoromethyl)phenyl)piperazin-1-yl)propan-1-one (1.2 g, 4 mmol, lequiv.). The resulting solution was heated to 80° C. and stirred 4h before cooling to room temperature. NaOH (1N aqueous solution, 3 mL) was added. The solution was diluted with EtOAc (30 mL) and washed with water (30 mL×2) and brine (30 mL). The organic phase was dried over Na2SO4. After removal of solvents, the residue was purified via flash chromatography (CH2Cl2:MeOH=20:1) to afford the desired product 5.2 ethyl 6-chloro-4-(4-(4-propionylpiperazin-1-yl)-3-(trifluoromethyl)phenylamino)quinoline-3-carboxylate (2g; 93%). LC-MS: (M+H): 622.20
