Versuchsvorschrift

To a stirred solution of 5-(4-{4-fluoro-3-[(3-methyl-2-furoyl)amino]phenoxy}pyridin-2-yl)-N-(3-oxopropyl)-1H-pyrrole-3-carboxamide (140 mg, 0.29 mmol) in 10 ml of anhydrous DMF were added L-proline methyl ester hydrochloride (96 mg, 0.58 mmol) and triethylamine (58 mg, 0.58 mmol). The mixture was stirred at room temperature for 30 minutes, followed by addition of 1M sodium cyanoborohydride solution in THF (0.60 ml, 0.60 mmol) and stirring was continued for another 30 minutes. The mixture was poured into 100 ml of water. The precipitates were filtered, washed with water and dried to give the crude, which was purified by silica gel flash chromatography eluting with 5% of MeOH in CHCl3 to give methyl 1-[3-({[5-(4-{4-fluoro-3-[(3-methyl-2-furoyl)amino]phenoxy}pyridin-2-yl)-1H-pyrrol-3-yl]carbonyl}amino)propyl]pyrrolidine-2-carboxylate as light beige solid. Yield: 70 mg, 40%.
