Versuchsvorschrift

(3-Morpholin-4-yl-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl-amine Palladium Acetate (0.029 g, 0.00013 mol) and Triphenylphosphine (0.042 g, 0.00016 mol) were dissolved in Tetrahydrofuran (2.0 mL) and the mixture was allowed to stir at room temperature for 10 minutes. (7-Bromo-pyrrolo[2,1-f][1,2,4]triazin-2-yl)-(3-morpholin-4-yl-phenyl)-amine (0.240 g, 0.000641 mol) was then added and the reaction was again allowed to stir for 10 minutes. 2-chloro-5-trifluoromethylphenylboronic acid (0.288 g, 0.00128 mol) was added followed by 0.9 M of Sodium carbonate in water (2 mL) and Ethanol (2.0 mL). The reaction mixture was then heated at 80° C. and was allowed to stir overnight. The reaction mixture was poured over saturated sodium chloride, and organics were extracted with ethyl acetate/dichloromethane. Combined organics were dried over sodium sulfate, filtered and reduced en vacuo. Because the desired product was not formed, 22.96 mg of (3-Morpholin-4-yl-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl-amine was purified by Gilson prep HPLC as a byproduct. (M+H)=296.14. 1H NMR (400 MHz, CDCl3) δ 9.47 (s, 1H), 8.62 (s, 1H), 7.98 (s, 1H), 7.88 (s, 1H), 7.36 (m, 2H), 7.08 (d, 1H, J=4.85 Hz), 6.91 (m, 2H), 4.02 (m, 4H), 3.41 (m, 2H).
