Procedure

To a solution of compound 5.2 ethyl 6-chloro-4-(4-(4-propionylpiperazin-1-yl)-3-(trifluoromethyl)phenylamino)quinoline-3-carboxylate (1 g, 1.6 mmol, lequiv.) in dioxane (5 mL) at room temperature was sequentially added 3-qunionline boronic acid 5.3 (350 mg, 2 mmol, 1.1 equiv.), PdCl2(Ph3P)2 (130 mg, 0.19 mmol, 0.1 equiv.), t-Bu-Xphos (78 mg, 0.19 mmol, 0.1 equiv.) and Na2CO3 (1N, 5.5 mL, 5.5 mmol, 3 equiv.). The mixture was degassed, sealed under argon, and heated overnight at 100° C. Upon cooling to room temperature, the mixture was diluted with EtOAc (20 mL), filtered through celite, and washed with EtOAc (20 mL×2). The resulting solution was concentrated and the residue was purified via flash chromagraphy (CH2Cl2:MeOH=30 :1) to afford the desired product 5.4 ethyl 4′-(4-(4-propionylpiperazin-1-yl)-3-(trifluoromethyl)phenylamino)-3,6′-biquinoline-3′-carboxylate (360 mg; 31%). LC-MS: (M+H): 535.20
