Diisopropylethylamine → N1-(3-Fluoro-4-(6-(2-morpholinopyridin-4-yl)pyrrolo[2,1-f][1,2,4]triazin-4-yloxy)phenyl)-N3-(4-fluorophenyl)malonamide

Participants

Reaction Steps

To a solution of 3-fluoro-4-(6-(2-morpholinopyridin-4-yl)pyrrolo[2,1-f][1,2,4]triazin-4-yloxy)benzenamine (15 mg, 0.037 mmol) and 3-(4-fluorophenylamino)-3-oxopropanoic acid (8 mg, 0.04 mmol, Compound A of Example 25) in DMF (1 mL) were added DIEA (0.1 mL, 0.57 mmol) and TBTU (13 mg, 0.04 mmol). The reaction mixture was stirred at room temperature overnight and then purified using preparative HPLC. The fraction containing the desired product was collected and concentrated in vacuo. The residue was neutralized with 1 N NH4OH and concentrated again. The solid that formed was filtered, washed with 1 N NH4OH, dissolved in MeOH/H2O, and lyophilized to give the title compound (8 mg, 37%). 1H NMR (DMSO-d6) δ 10.49 (s, 1H), 10.23 (s, 1H), 8.63 (s, 1H), 8.55 (s, 1H), 8.06 (s, 1H), 8.00 (d, 1H, J=7.5 Hz), 7.70 (m, 1H), 7.50 (m, 2H), 7.30–7.45 (m, 3H), 7.04–7.17 (m, 3H), 6.85–6.92 (m, 2H), 3.36 (s, 4H), 3.44 (s, 6H); MS(ESI) m/z 586.2 (M+H)+.
