Reaction Steps

Into an 8-dram vial, (2-{2-[4-(4-Methyl-piperazin-1-yl)-phenylamino]-pyrrolo[2,1-f][1,2,4]triazin-7-yl}-phenoxy)-acetic acid tert-butyl ester (0.180 g, 0.350 mmol), Methylene chloride (5.0 mL, 78 mmol), and Trifluoroacetic Acid (1.00 mL, 13.0 mmol) were added. The reaction was stirred at room temperature overnight. The reaction was partitioned with saturated NaHCO3 and DCM. The organic was separated, washed with Brine and dried over Na2SO4. The solid was filtered and washed with DCM. 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 (2-{2-[4-(4-Methyl-piperazin-1-yl)-phenylamino]-pyrrolo[2,1-f][1,2,4]triazin-7-yl}-phenoxy)-acetic acid as a yellow solid (32 mg, 20%). LCMS (E/I+) 459.14 (M+H).
