Participants

Reaction Steps

Methanesulfonyl chloride (7.5 μl, 0.10 mmol) was added to a solution of 2-((3-((3R,4R)-4-amino-3-((triisopropylsilyl)oxy)piperidin-1-yl)-2-chloro-5-cyanophenyl)amino)-4-(cyclopropylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (25 mg, 0.040 mmol) and triethylamine (17 μl, 0.120 mmol) in dichloromethane (1 mL) and the reaction solution was stirred at room temperature overnight. The crude product was purified by flash chromatography on silica gel using an automated ISCO system (12 g column, eluting with 0-40% ethyl acetate/dichloromethane). N-((3R,4R)-1-(2-chloro-5-cyano-3-((7-cyano-4-(cyclopropylamino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)-3-((triisopropylsilyl)oxy)piperidin-4-yl)methanesulfonamide (28 mg) was obtained as a white solid.
