Participants

Reaction Steps

A mixture of 5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrole-3-carboxylic acid (500 mg, 1.12 mmol), HATU (467 mg, 1.23 mmol) and N,N-diisopropylethylamine (322 mg, 2.5 mmol) in anhydrous DMF (10 ml) was stirred at room temperature for 10 minutes, followed by addition of aminoacetaldehyde diethyl acetal (194 mg, 1.46 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 N-(2,2-diethoxyethyl)-5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrole-3-carboxamide as white solid. Yield: 580 mg, 92%.
