Procedure

A mixture of 7-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]thieno[3,2-b]pyridine-2-carboxylic acid (300 mg, 0.69 mmol), HATU (288 mg, 0.76 mmol) and N,N-diisopropylethylamine (196 mg, 1.52 mmol) in anhydrous acetonitrile (10 ml) was stirred at room temperature for 30 minutes, followed by addition of N-Boc-1,3-propanediamine (180 mg, 1.03 mmol). The mixture was stirred for another 30 minutes and poured into 100 ml of water with vigorous stirring. 2M HCl was added dropwise until pH=6. The precipitates were filtered, washed with water and dried in vacuo to give tert-butyl {3-[({7-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]thieno[3,2-b]pyridin-2-yl}carbonyl)amino]propyl}carbamate as brown solid. Yield: 380 mg, 93%.
