Reaction Steps

Into a 8-dram vial, Palladium Acetate (0.00772 g, 0.0344 mmol), Triphenylphosphine (0.0264 g, 0.100 mmol) and 1,4-Dioxane (1 mL) were added and stirred at room temperature for 10 minutes. (7-Bromo-pyrrolo[2,1-f][1,2,4]triazin-2-yl)-[4-(4-methyl-piperazin-1-yl)-phenyl]-amine (0.250 g, 0.646 mmol), 5-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyridine-3-carbaldehyde (0.3009 g, 1.291 mmol), N,N-Dimethylformamide (1 mL) and 1.50 M of Sodium carbonate in Water (5 mL, 8 mmol) were added. The reaction mixture was heated at 90° C. overnight. The reaction was cooled to room temperature. Solvent was removed under vacuum to give a yellow solid. The resulting solid was partitioned with water and DCM. The organic was separated, washed with Brine and dried over Na2SO4. The solid was filtered and washed with DCM. The solvent was removed under vacuum. The reaction mixture was purified via ISCO column chromatography with DCM and methanol as eluant (5 to 25% methanol). The collected fractions afforded 5-{2-[4-(4-Methyl-piperazin-1-yl)-phenylamino]-pyrrolo[2,1-f][1,2,4]triazin-7-yl}-pyridine-3-carbaldehyde as a yellow solid (65 mg, 24%).
