実験手順
To a round bottom flask charged with 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 (0.27 g, 0.474 mmol) in wet dichloromethane (3.16 ml) was added Dess-Martin periodinate (0.402 g, 0.947 mmol). The reaction mixture was stirred at room temperature 2.5 h. The reaction mixture was diluted with dichloromethane and quenched by the addition of sodium thiosulfate doped saturated aqueous sodium bicarbonate (25 g/100 mL). The mixture was stirred until 2 clear layers were visible. The mixture was transferred to a separatory funnel and the aqueous layer was extracted with dichloromethane (3×). The combined organics were washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. 2-((2-Chloro-5-cyano-3-(4-oxopiperidin-1-yl)phenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (0.2465 g) was isolated as a yellow solid.
