Reaction Steps

To a solution of 5-(2-benzyl-2H-indazol-6-yl)-7-(4-bromobutyl)pyrrolo[2,1-f][1,2,4]triazin-4-amine (440 mg, 0.93 mmol) in DMF (5.0 mL) was added pyrrolidine (155 μL, 1.86 mmol), triethylamine (387 μl, 2.78 mmol), and sodium iodide (1.4 mg, 0.009 mmol). The reaction was heated (55° C.) for 17 h and then cooled to rt. The mixture was partitioned between ethyl acetate (25 mL) and water (25 mL). The layers were separated and the organic was washed with water (2×20 mL), brine, dried (Na2SO4) and evaporated to afford 360 mg (84%) of the desired product. 1H NMR (300 MHz, DMSO-d6) δ 8.53 (s, 1 H), 7.87 (s, 1 H), 7.78 (d, 1 H), 7.56 (s, 1 H), 7.36-7.26 (m, 5 H), 7.13 (dd, 1 H), 6.57 (s, 1 H), 5.64 (s, 2 H), 2.88 (t, 2 H), 2.42-2.33 (m, 6 H), 1.78-1.66 (m, 2 H), 1.67-1.60 (m, 4 H), 1.57-1.46 (m, 2H); ES-MS m/z 466.3 [M+H]+, HPLC RT (min) 2.20.
