Diisopropylethylamine → HCID 71542164, compound

Participants

Reaction Steps

To a stirred solution of 5-(4-{4-fluoro-3-[(3-methyl-2-furoyl)amino]phenoxy}pyridin-2-yl)-1H-pyrrole-3-carboxylic acid (300 mg, 0.71 mmol) in 10 ml of anhydrous DMF were added HATU (324 mg, 0.85 mmol) and N,N-diisopropylethylamine (200 mg, 1.55 mmol). The mixture was stirred at room temperature for 10 minutes, followed by addition of 1-amino-3,3-diethoxypropane (157 mg, 1.06 mmol), and stirring was continued for another 10 minutes. The mixture was poured into 100 ml of water with vigorous stirring. The precipitates were filtered, washed with water and dried in vacuo to give N-(3,3-diethoxypropyl)-5-(4-{4-fluoro-3-[(3-methyl-2-furoyl)amino]phenoxy}pyridin-2-yl)-1H-pyrrole-3-carboxamide as white solid. Yield: 380 mg, 97%.
