実験手順

To (+/−)-N-((3R,4R)-3-((tert-butyldimethylsilyl)oxy)-1-(2-chloro-5-cyano-3-((7-cyano-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)piperidin-4-yl)-2-chloroacetamide (43 mg, 0.055 mmol) in THF (1 mL) was added TBAF (1M in THF, 0.112 mL, 0.112 mmol) and the reaction solution was stirred at room temperature overnight. LCMS showed completion of reaction. Solvent was evaporated and the crude product was purified by flash chromatography on silica gel using an automated ISCO system (24 g column, eluting with 0.5-4% methanol/dichloromethane) to give (+/−)-2-chloro-N-((3R,4R)-1-(2-chloro-5-cyano-3-((7-cyano-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)-3-hydroxypiperidin-4-yl)acetamide (22 mg) as a white solid.
