Procedure

To a stirred suspension of 7-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]thieno[3,2-b]pyridine-2-carboxylic acid (120 mg, 0.26 mmol) in 10 ml of anhydrous THF were added HATU (118 mg, 0.31 mmol) and N,N-diisopropylethylamine (100 mg, 0.78 mmol). The mixture was heated at 60° C. for 5 minutes, followed by addition of ethyl 4-aminobutyrate hydrochloride (67 mg, 0.40 mmol). The mixture was stirred for another 10 minutes, cooled to room temperature and poured into 100 ml of water with vigorous stirring. 1M HCl was added dropwise until pH=5. The precipitates were filtered, washed with water and dried in vacuo to give ethyl 4-[({7-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]thieno[3,2-b]pyridin-2-yl}carbonyl)amino]butanoate as white solid. Yield: 150 mg, 100%.
