Versuchsvorschrift

To a stirred suspension of 5-tert-butoxy-2-[({5-[4-(2-fluoro-5-{[(2-fluoro-5-methylphenyl)amino]carbonyl}phenoxy)pyridin-2-yl]-1H-pyrrol-3-yl}carbonyl)amino]-5-oxopentanoic acid (150 mg, 0.24 mmol) in 10 ml of anhydrous tetrahydrofuran were added HATU (109 mg, 0.29 mmol) and N,N-diisopropylethylamine (93 mg, 0.72 mmol). The mixture was heated at 60° C. for 15 minutes and cooled to room temperature, followed by addition of 2M ethylamine solution in THF (0.18 ml, 0.36 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-(2-fluoro-5-{[(2-fluoro-5-methylphenyl)amino]carbonyl}phenoxy)pyridin-2-yl]-1H-pyrrol-3-yl}carbonyl)amino]-5-oxopentanoate as white solid. Yield: 100 mg, 64%.
