Reaction Steps
Into an 8-dram vial, 2-methoxy-4-[trans-4-(morpholin-4-yl)cyclohexyl]aniline (0.125 g, 0.430 mmol), Trifluoro-methanesulfonic acid 7-(2-methoxy-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl ester (98 mg, 0.26 mmol), N,N-Diisopropylethylamine (0.0749 mL, 0.430 mmol), and 1-Methoxy-2-propanol (0.70 mL, 7.2 mmol) were added. The reaction mixture was heated at 120° C. for 6 hours. The solvent was removed under vacuum. The reaction mixture was purified via HPLC reverse phase chromatography with 0.1% TFA in Water and 0.1% TFA in ACN. The collected fractions were lyophilized to give N-{2-methoxy-4-[trans-4-(morpholin-4-yl)cyclohexyl]phenyl}-7-(2-methoxyphenyl)pyrrolo[2,1-f][1,2,4]triazin-2-amine as a yellow solid (65 mg, 48%).
