Reaction Steps

Into an 8-dram vial, Trifluoro-methanesulfonic acid 7-[2-(methanesulfonyl-methyl-amino)-phenyl]-pyrrolo[2,1-f][1,2,4]triazin-2-yl ester (88.0 mg, 0.195 mmol), 2-Methoxy-4-morpholin-4-ylmethyl-phenylamine (0.174 g, 0.782 mmol), N,N-Diisopropylethylamine (0.136 mL, 0.782 mmol), and 1-Methoxy-2-propanol (0.880 mL, 9.00 mmol) were added. The reaction mixture was heated at 120° C. for 4 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 concentrated under vacuum to give a glassy solid. The solid was triturated with Et2O to give N-{2-[2-(2-Methoxy-4-morpholin-4-ylmethyl-phenylamino)-pyrrolo[2,1-f][1,2,4]triazin-7-yl]-phenyl}-N-methyl-methanesulfonamide as a yellow solid (46 mg, 37%).
