실험 절차

To ethyl((3R,4R)-1-(2-chloro-5-cyano-3-((7-cyano-4-(ethyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)-3-hydroxypiperidin-4-yl)carbamate (50 mg, 0.068 mmol), in DCE (0.8 mL) was added anisole (0.1 mL, 0.915 mmol) and TFA (0.5 mL, 6.49 mmol); the mixture stirred 2 h at 25° C. and solvent was removed. 2N NH3/MeOH (5 ml) was added and the mixture stirred for 30 min at 25° C. The solution was stored at −20° C. and a white precipitate formed. The material was collected by filtration, washed with 20 ml cold MeOH, 5 ml ether and dried under air-suction for 0.5 h to afford ethyl ((3R,4R)-1-(2-chloro-5-cyano-3-((7-cyano-4-(ethylamino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)-3-hydroxypiperidin-4-yl)carbamate (10 mg).
