실험 절차

To a stirred suspension of 5-tert-butoxy-2-({[5-(4-{3-[(3-methyl-2-furoyl)amino]phenoxy}pyridin-2-yl)-1H-pyrrol-3-yl]carbonyl}amino)-5-oxopentanoic acid (100 mg, 0.17 mmol) in 10 ml of anhydrous tetrahydrofuran were added HATU (76 mg, 0.20 mmol) and N,N-diisopropylethylamine (66 mg, 0.51 mmol). The mixture was heated at 60° C. for 15 minutes and cooled to room temperature, followed by addition of 2-Methylamine solution in THF (0.25 ml, 0.50 mmol). The mixture was stirred for another 5 minutes and poured into 100 ml of water with vigorous stirring. 1M HCl was added dropwise until pH=4. 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% methanol in chloroform to give tert-butyl 5-(ethylamino)-4-({[5-(4-{3-[(3-methyl-2-furoyl)amino]phenoxy}pyridin-2-yl)-1H-pyrrol-3-yl]carbonyl}amino)-5-oxopentanoate as white solid. Yield: 82 mg, 78%.
