Procedure

A mixture of 3-methyl-2-furoic acid (60 mg, 0.48 mmol), HBTU (198 mg, 0.52 mmol) and N,N-diisopropylethylamine (129 mg, 1.0 mmol) in anhydrous DMF (10 ml) was stirred at room temperature for 10 minutes, followed by addition of 3-{[2-(1H-pyrrol-2-yl)pyridin-4-yl]oxy}aniline (100 mg, 0.40 mmol). The mixture was stirred at 70° C. for 3 hours and poured into 100 ml of water. The precipitates were filtered, washed with water and dried in vacuo to give the crude, which was purified by silica gel chromatography eluting with 3-5% MeOH/CHCl3 to give 3-methyl-N-(3-{[2-(1H-pyrrol-2-yl)pyridin-4-yl]oxy}phenyl)-2-furamide as white solid. Yield: 52 mg, 36%.
