A mixture of 7-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]thieno[3,2-b]pyridine-2-carboxylic acid (100 mg, 0.22 mmol), HATU (90 mg, 0.24 mmol) and N,N-diisopropylethylamine (55 mg, 0.43 mmol) in anhydrous acetonitrile (10 ml) was stirred at room temperature for 30 minutes, followed by addition of 3-(4-methylpiperazin-1-yl)propan-1-amine (40 mg, 0.25 mmol). The mixture was stirred for another 10 minutes and poured into 100 ml of water. The precipitates were filtered, washed with water and dried in vacuo to give 7-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]-N-[3-(4-methylpiperazin-1-yl)propyl]thieno[3,2-b]pyridine-2-carboxamide as brown solid. Yield: 110 mg, 84%.
