Reaction Steps

To a stirred solution of 5-(2-benzyl-2H-indazol-6-yl)-7-(octahydropyrazino[2,1-c][1,4]oxazin-3-yl)pyrrolo[2,1-f][1,2,4]triazin-4-amine (85 mg, 0.18 mmol) and triethylamine (49 μL, 0.35 mmol) in DMF (1 mL) at −78° C., iodomethane (177 μL, 0.17 mmol, 1.0M in DMF) was added. The reaction was allowed to stir for 1 h while warming to rt. The mixture was partitioned between ethyl acetate (30 mL) and pH 14 saturated aqueous NaCl (10 mL). The layers were separated and the organic phase was washed, dried (Na2SO4), and concentrated to dryness. The residue was triturated with Et2O to obtain 30 mg (34%) of the desired product. 1H-NMR (DMSO-d6) 8.53 (s, 1H), 7.90 (s, 1H), 7.78 (d, 1H), 7.57 (s, 1H), 7.35-7.28 (m, 5H), 7.11 (d, 1H), 6.70 (s, 1H), 5.64 (s, 2H), 5.11 (dd, 1 H), 3.75 (dd, 1 H), 3.37-3.26 (m, 1H), 2.98 (dd, 1H), 2.70-2.65 (m, 2H), 2.56-2.50 (m, 1H), 2.47-2.30 (m, 1H), 2.26-2.18 (m, 2H), 2.14 (s, 3H), 2.11-2.01 (m, 1H), 1.61 (t, J=10.5 Hz, 1H); LC-MS [M+H]+=495, RT=2.10 min.
