Procedure

Using a procedure similar to that of Example 111 with 7-(3-aminomethyl-phenyl)-5-(2-benzyl-2H-indazol-6-yl)-pyrrolo[2,1-f][1,2,4]triazin-4-ylamine and cyclobutanone as starting materials, 39 mg (17%) of the desired product was isolated. 1H NMR (300 MHz, DMSO-d6) δ 8.80 (s, 1 H), 8.05 (d, 2 H), 8.0 (s, 1 H), 7.90 (d, 1 H), 7.70 (s, 1 H), 7.60-7.40 (m, 7 H), 7.25 (d, 1 H), 7.20 (s, 1 H), 5.70 (s, 2 H), 3.80 (m, 2 H), 2.10 (m, 1 H), 2.00 (m, 2 H), 1.70-1.40 (m, 4 H); ES-MS m/z 500.2 [M+H]+, HPLC RT (min) 2.46.
