Versuchsvorschrift

In a round bottomed flask ethyl 6-bromo-1-[2-(dimethylamino)ethyl]-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate (Intermediate 21, 200 mg, 0.54 mmol), 6-(3-ethylureido)-4-(4-(trifluoromethyl)thiazol-2-yl)pyridin-3-ylboronic acid (Intermediate 9, 288 mg, 0.65 mmol) and sodium carbonate (115 mg, 1.08 mmol) were combined and suspended in dimethylformamide (10 mL) and purged with argon gas for 10 min. Tetrakis (triphenylphosphine) palladium (62 mg, 0.05 mmol) was added under argon atmosphere and the reaction mixture was heated to 90° C. for 2 h. After completion of the reaction, the reaction mixture was cooled to room temperature and filtered through celite. The filtrate was poured into water and was stirred for 20 min. The obtained solid was filtered and washed with water then dried to afford 110 mg (33%) of ethyl 1-[2-(dimethylamino)ethyl]-6-{6-[(ethylcarbamoyl)amino]-4-[4-(trifluoromethyl)-1,3-thiazol-2-yl]pyridin-3-yl}-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate.
