A mixture of 7-azetidin-3-yl-5-(2-benzyl-2H-indazol-6-yl)pyrrolo[2,1-f][1,2,4]triazin-4-amine (20 mg, 0.051 mmol), N,N-dimethylglycine (5.7 mg, 0.056 mmol), EDCl (11.6 mg, 0.061 mmol), HOBt (8.2 mg, 0.061 mmol), and N,N-diisopropylethylamine (26 μL, 0.15 mmol) in DMF (1 mL) was stirred at rt for 16 h. The crude reaction mixture was purified via preparative HPLC using a gradient elution from 15% to 45% acetonitrile in water followed by filtration through an acidic resin, washing with MeOH. The product was eluted with 2M NH3 in MeOH and the filtrate was concentrated to provide 5 mg (21%) of the desired product. 1H NMR (400 MHz, CD3OD) δ 8.37 (s, 1 H), 7.79-7.85 (m, 2 H), 7.67 (s, 1 H), 7.29-7.37 (m, 5 H), 7.25 (d, 1 H), 6.81 (s, 1 H), 5.65 (s, 2 H), 4.70 (t, 1 H), 4.25-4.54 (m, 4 H), 3.18 (s, 2 H), 2.38 (s, 6 H); ES-MS m/z 481.10 [M+H]+, HPLC RT (min) 2.07.
