Procedure

Into a 8-dram vial, (7-Bromo-pyrrolo[2,1-f][1,2,4]triazin-2-yl)-[4-(4-methyl-piperazin-1-yl)-phenyl]-amine (66.6 mg, 0.000172 mol), [3-(Aminomethyl)-pyridine (22.33 mg, 0.2065 mmol) Palladium Acetate (4.00 mg, 0.0178 mmol), 9,9-Dimethyl-4,5-bis(diphenylphosphino)xanthene (30.0 mg, 0.0518 mmol), and Cesium Carbonate (240.0 mg, 0.7366 mmol) were added. The mixture was purged with nitrogen for 15 minutes. 1,4-Dioxane (2.00 mL) was added. The reaction vessel was sealed and heated at 120° C. for 2 hours. The reaction mixture was partitioned with DCM. The solid was filtered through celite and washed with DCM. The filtrate was evaporated to give a semi-solid. The reaction mixture was purified via HPLC reverse phase chromatography with 0.1% TFA in Water and 0.1% TFA in ACN (0 to 20% ACN). The collected fractions were lyophilized to give N(2)-[4-(4-Methyl-piperazin-1-yl)-phenyl]-N(7)-pyridin-3-ylmethyl-pyrrolo[2,1-f][1,2,4]triazine-2,7-diamine a solid. The solid was triturated with Et2O to give a yellow solid 78 mg, 85%). LCMS (E/I+) 415.17 (M+H). NMR 1H (DMSO-d6)-9.80 (bs, 1H), 9.34 (s, 1H), 8.70 (s, 1H), 8.57 (s, 1H), 8.36 (s, 1H), 7.89 (d, 1H, J=7.04 Hz), 7.65 (d, 2H, J=8.04 Hz), 7.54 (t, 1H, J=5.53 Hz), 7.49 (bs, 1H), 7.13 (s, 1H), 6.99 (d, 2H, J=8.04 Hz), 6.33 (s, 1H), 4.72 (s, 2H), 3.75 (d, 2H, J=12.56 Hz), 3.54 (d, 2H, J=11.06 Hz), 3.18 (bs, 2H), 2.6-3.00 (m, 5H).
