실험 절차

(I13D): To a round bottom flask charged with 2-((3-(4-((tert-butyldimethylsilyl)oxy)piperidin-1-yl)-2-chloro-5-cyanophenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (I13C) (1.446 g, 2.113 mmol) in tetrahydrofuran (21.13 ml) and cooled to 0° C. was added TBAF (4.23 ml, 4.23 mmol). The reaction mixture was stirred at room temperature 2 d. The reaction mixture was poured into a separatory funnel containing saturated aqueous sodium bicarbonate and ethyl acetate. The aqueous layer was extracted with ethyl acetate (3×). The combined organics were washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The crude residue was taken up in dichloromethane. A white precipitate was isolated by filtration. The filtrate was purified by column chromatography on the ISCO system (40 g, 0-50% EtOAc/CH2Cl2). The precipitate was combined with the column isolate to provide 2-((2-chloro-5-cyano-3-(4-hydroxypiperidin-1-yl)phenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (0.816 g) as a white solid.
