Procedure

A mixture of 5-(2-benzyl-2H-indazol-6-yl)-7-piperidin-4-ylpyrrolo[2,1-f][1,2,4]triazin-4-amine (150 mg, 0.33 mmol), N,N-dimethylglycine (40 mg, 0.39 mmol), EDCl (69 mg, 0.36 mmol), HOBt (48 mg, 0.36 mmol), and N,N-diisopropylethylamine (227 μL, 1.30 mmol) in DMF (2 mL) was stirred at rt for 6 h. An additional 0.5 eq. of N,N-dimethylglycine was added and the mixture continued to stir at rt for 16 hr. The crude reaction mixture was purified via preparative HPLC using a gradient elution from 15% to 40% acetonitrile in water to provide 39 mg (24%) of the desired product. 1H NMR (400 MHz, DMSO-d6) δ 8.56 (s, 1 H), 7.92 (s, 1 H), 7.81 (d, 1 H), 7.66 (s, 1 H), 7.28-7.39 (m, 5 H), 7.15 (dd, 1 H), 6.60 (s, 1 H), 5.67 (s, 2 H), 4.32 (dd, 1 H) 3.33-3.46 (m, 1 H), 3.01-3.20 (m, 4 H), 2.66-2.78 (m, 1 H), 2.19 (s, 6 H), 2.05 (d, 2 H), 1.44-1.75 (m, 2 H); ES-MS m/z 509.23 [M+H]+, HPLC RT (min) 2.12.
