Procedure

A solution of tert-butyl 4-{[1-(1,3-dimethoxypropan-2-yl)-6-iodo-4-oxo-1,4-dihydroquinolin-3-yl]carbonyl}piperazine-1-carboxylate (Intermediate 79, 400 mg, 0.68 mmol) in dimethylformamide (15 mL) was purged argon gas, then tetrakis(triphenylphosphine)palladium (69.25 mg, 0.06 mmol) followed by 1-ethyl-3-{5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-4-[4-(trifluoromethyl)-1,3-thiazol-2-yl]pyridin-2-yl}urea (Intermediate 17, 360 mg, 0.82 mmol) was added. The mixture was stirred at room temperature and sodium carbonate (217 mg, 2.05 mmol) which was dissolved in minimum amount of water was added and the reaction mixture was heated to 95° C. for 3 h. After completion of the reaction, the reaction mixture was cooled to room temperature, filtered through celite, and the filtrate was poured into water (200 mL) and stirred for 30 min. The obtained solid was filtered and dried to give the crude compound. The crude was purified by column chromatography eluting with a gradient of 30% ethyl acetate/petroleum ether to 60% ethyl acetate/petroleum ether to afford 260 mg (49%) of tert-butyl 4-{[1-(1,3-dimethoxypropan-2-yl)-6-{6-[(ethylcarbamoyl)amino]-4-[4-(trifluoromethyl)-1,3-thiazol-2-yl]pyridin-3-yl}-4-oxo-1,4-dihydroquinolin-3-yl]carbonyl}piperazine-1-carboxylate.
