Versuchsvorschrift

To around bottom flask charged with (+/−)-2-((3-(2-(((tert-butyldimethylsilyl)oxy)methyl)morpholino)-2-chloro-5-cyanophenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (1.576 g, 2.251 mmol) in THF (11.26 ml) was added TBAF (3.38 ml, 3.38 mmol). The reaction mixture was stirred at room temperature 2.5 h. The reaction mixture was poured into a separatory funnel containing 1:1 saturated aqueous ammonium chloride and ethyl acetate. The aqueous layer was extracted with ethyl acetate (2×). The combined organics were dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The crude solid was taken up in minimal dichloromethane and purified by column chromatography on the ISCO system (80 g, 0-50% EtOAc/CH2Cl2). (+/−)-2-((2-Chloro-5-cyano-3-(2-(hydroxymethyl)morpholino)phenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (0.926 g) was isolated as a yellow solid.
