Reaction Steps

1-{4-[4-amino-7-(3-bromopropyl)pyrrolo[2,1-f][1,2,4]triazin-5-yl]-2-fluorophenyl}-3-[2-fluoro-5-(trifluoromethyl)phenyl]urea (Example 193 step 1) (50 mg, 0.088 mmol) and (2S)-2-(methoxymethyl)pyrrolidine (36 uL, 0.263 mmol) were added to a vial. DMF was added (1 mL) followed by triethylamine (15 uL, 0.109 mmol) and KI (spatula tip). The vial was capped and the reaction heated at 55° C. for two hours. Upon cooling the product precipitated out of solution. The solids were collected by filtration and rinsed with ether to yield 35 mg (65%) of clean product. 1H-NMR (DMSO-d6) δ 9.41 (s, 1H), 9.25 (s, 1H), 8.65 (d, J=7.2 Hz, 1H), 8.26 (t, J=8.4 Hz, 1H), 7.89 (s, 1H), 7.55 to 7.21 (m, 4H), 6.57 (s, 1H), 3.32 (s, 3H), 3.18 to 2.83 (m, 7H), 2.37 to 1.45 (m, 5H); MS [M+H]+=604.2; LCMS RT=2.59
