Procedure

To a round bottom flask charged with 2-((2-chloro-5-cyano-3-(2-(morpholine-4-carbonyl)morpholino)phenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (64.9 mg, 0.097 mmol) in dichloromethane (485 μl) was added anisole (21.19 μl, 0.194 mmol), followed by TFA (224 μl, 2.91 mmol). The reaction mixture was stirred at room temperature for 16 h. Additional TFA (224 μl, 2.91 mmol) was added. Stir at room temperature ON. Additional TFA (224 μl, 2.91 mmol) was added and the reaction mixture was stirred at room temperature ON. Excess TFA was removed by concentration in vacuo. The crude residue was taken up in methanol and free based using a Phenomenex Strata 1 g SCX column. The column was flushed with 3 column volumes methanol and 3 column volumes 3.5 N ammonia/methanol. The ammonia layers were concentrated in vacuo. The crude material was purified by neutral phase preparatory LC/MS chromatography to provide (+/−)2-((2-chloro-5-cyano-3-(2-(morpholine-4-carbonyl)morpholino)phenyl)amino)-4-(cyclopropylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (13 mg).
