A mixture of 3-methyl-2-furoic acid (22 mg, 0.18 mmol), HATU (73 mg, 0.19 mmol) and N,N-diisopropylethylamine (45 mg, 0.35 mmol) in anhydrous DMF (10 ml) was stirred at room temperature for 10 minutes, followed by addition of methyl 5-(4-((3-aminophenyl)amino)pyridin-2-yl)-1H-pyrrole-3-carboxylate (50 mg, 0.16 mmol). The mixture was stirred at room temperature for 3 hours and poured into 100 ml of water. The precipitates were filtered, washed with water and dried in vacuo to give methyl 5-[4-({3-[(3-methyl-2-furoyl)amino]phenyl}amino)pyridin-2-yl]-1H-pyrrole-3-carboxylate as off-white solid. Yield: 10 mg, 15%.
