Procedure

A solution of 5-(2-benzyl-2H-indazol-6-yl)-7-(3-bromopropyl)pyrrolo[2,1-f][1,2,4]-triazin-4-ylamine (2.62 g, 5.68 mmol), pyrrolidine (808 mg, 11.36 mmol, 2.0 eq), triethylamine (575 mg, 5.68 mmol, 1.0 eq); and sodium iodide (85 mg, 0.56 mmol, 0.1 eq) in anhydrous DMF (28 mL) was stirred at 55° C. for 17 h. The reaction mixture was partitioned between EtOAc and water, and the organic layer was washed with 50% aq. brine (3×), dried over Na2SO4, filtered, and concentrated at reduced pressure. The crude was triturated from MeOH, filtered, and washed with cold MeOH and ether to provide 2.16 g (84.2%) of the desired product as a white solid. 1H-NMR (DMSO-d6) 8.54 (s, 1H), 7.89 (s, 1H), 7.80 (d, 1H), 7.58 (s, 1H), 7.36 to 7.30 (m, 5H), 7.14 (d, 1H), 6.59 (s, 1H), 5.65 (s, 2H), 2.90 (t, 2H), 2.48 to 2.39 (m, 6H), 1.87 to 1.83 (m, 2H), 1.67 to 1.64 (m, 4H); LC-MS [M+H]+=452, RT=2.14 min.
