実験手順

2-chloroacetyl chloride (7.56 mg, 0.067 mmol) in dichloromethane (0.5 mL) was added to a mixture of (+/−)-2-((3-((3R,4R)-4-amino-3-((tert-butyldimethylsilyl)oxy)piperidin-1-yl)-2-chloro-5-cyanophenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (Example 171D), (39 mg, 0.056 mmol) and triethylamine (0.016 mL, 0.112 mmol) in dichloromethane (1 mL) at 0° C. and the reaction mixture was stirred at for 1 h. The reaction mixture was diluted with dichloromethane and washed with water. The organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo. The crude product was purified by flash chromatography on silica gel using an automated ISCO system (12 g column, eluting with 5-40% ethyl acetate/dichloromethane to afford (+/−)-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) as a white solid.
