Reaction Steps

To a round bottom flask charged with (+/−)-2-((2-chloro-5-cyano-3-(2-(((4-methoxybenzyl)amino)methyl)morpholino)phenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (38.9 mg, 0.055 mmol) in tetrahydrofuran (276 μl) was added triethylamine (13.84 μl, 0.099 mmol) and methanesulfonyl chloride (5.59 μl, 0.072 mmol). The reaction mixture was stirred at room temperature ON. The reaction mixture was diluted with ethyl acetate and transferred to a separatory funnel containing saturated aqueous sodium bicarbonate. The aqueous layer was extracted with ethyl acetate (3×). The combined organics were dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The crude material was taken forward into the deprotection.
