Procedure

To a round bottom flask charged with 2-((2-chloro-5-cyano-3-(4-((3,3-difluorocyclobutyl)amino)piperidin-1-yl)phenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (34.9 mg, 0.053 mmol) in dichloromethane (530 μl) was added anisole (116 μl, 1.060 mmol), followed by the slow addition of trifluoroacetic acid (408 μl, 5.30 mmol). The reaction mixture was stirred at room temperature 2 d. Excess TFA was removed in vacuo. The crude residue was taken up in MeOH and free based using a Phenomenex Strata 1 g SCX column. The crude solid was purified via preparative LC/MS and provided 2-((2-chloro-5-cyano-3-(4-((3,3-difluorocyclobutyl)amino)piperidin-1-yl)phenyl)amino)-4-(cyclopropylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (3.4 mg).
