Versuchsvorschrift

A solution of] (4-{3-Methoxy-4-[7-(2-methoxy-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-ylamino]-phenyl}-piperidin-1-yl)-acetic acid tert-butyl ester (73 mg, 0.13 mmol) in 2 mL of 4N HCl in dioxane was stirred at RT. After 18 h, solvent was evaporated and the mixture was triturated with ether. A solid was obtained which was filtered, washed with ether (twice) and dried. The product, (4-{3-Methoxy-4-[7-(2-methoxy-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-ylamino]-phenyl}-piperidin-1-yl)-acetic acid was isolated as a pale yellow hygroscopic solid (54 mg, 82%). LCMS (E/I+) 488 (M+H). NMR 1H (DMSO-d6)-10.1 (br s, 1H), 8.96 (s, 1H0, 8.05 (d, 1H, J=8.24 Hz), 7.81 (d, 1H, J=7.49 Hz), 7.68 (s, 1H), 7.46 (m, 1H), 7.41 (d, 1H, J=7.96 Hz), 7.21 (d, 1H, J=8.34 Hz), 7.11 (d, 1H, J=7.45 Hz), 7.08 (m, 1H), 6.98 (m, 2H), 6.70 (d, 1H, J=7.32 Hz), 4.16 (br s, 2H), 4.05-3.1 (series of m and s along with the water peak, 10H), 2.8 (m, 1H), 2.03 (m, 4H).
