2-((2-chloro-5-cyano-4-(3-hydroxypropyl)phenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (30 mg, 0.057 mmol) was taken up in DCE (0.6 mL) and anisole (0.031 mL, 0.284 mmol) was added, followed by TFA (0.175 mli, 2.268 mmol). The reaction was stirred at room temperature overnight. LCMS indicates formation of the TFA ester. The solvent was removed in vacuo and the material dissolved in 2N NH3 in MeOH. The solution was stirred at room temperature for 30 min. The solvent was removed in vacuo and the material was triturated with Et2O to remove the anisole. The material was purified by preparative HPLC to provide 2-((2-chloro-5-cyano-4-(3-hydroxypropyl)phenyl)amino)-4-(cyclopropylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (6.2 mg).
