Participants

Reaction Steps

To a stirred solution of 5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-N-(3-oxopropyl)-1H-pyrrole-3-carboxamide (100 mg, 0.20 mmol) in 10 ml of anhydrous DMF were added 4-hydroxypiperidine (30 mg, 0.30 mmol) and acetic acid (10 mg, 0.17 mmol). The mixture was stirred at room temperature for 30 minutes, followed by addition of 1M sodium cyanoborohydride solution in THF (0.30 ml, 0.30 mmol) and stirring was continued for one more hour. 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 20% of MeOH in CHCl3 to give 5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-N-[3-(4-hydroxypiperidin-1-yl)propyl]-1H-pyrrole-3-carboxamide as white solid.
