Hydrochloric Acid → N-(3-{[2-(4-{[(3S)-3-hydroxypyrrolidin-1-yl]carbonyl}-1H-pyrrol-2-yl)pyridin-4-yl]oxy}phenyl)-3-methyl-2-furamide

Participants

Reaction Steps

A mixture of 5-(4-{3-[(3-methyl-2-furoyl)amino]phenoxy}pyridin-2-yl)-1H-pyrrole-3-carboxylic acid (60 mg, 0.15 mmol), HATU (68 mg, 0.18 mmol) and N,N-diisopropylethylamine (43 mg, 0.33 mmol) in anhydrous DMF (10 ml) was stirred at room temperature for 10 minutes, followed by addition of (S)-3-pyrrolidinol (16 mg, 0.18 mmol). The mixture was stirred for another 10 minutes and poured into 100 ml of water. 2M HCl was added dropwise until pH=4˜5. The precipitates were filtered, washed with water and dried in vacuo to give N-(3-{[2-(4-{[(3S)-3-hydroxypyrrolidin-1-yl]carbonyl}-1H-pyrrol-2-yl)pyridin-4-yl]oxy}phenyl)-3-methyl-2-furamide as white solid. Yield: 40 mg, 56%.
