Methyl chloroformate → methyl 5-(2-chloro-5-cyano-3-((7-cyano-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)octahydro-1H-pyrrolo[3,2-c]pyridine-1-carboxylate

Reaction Steps

Methyl chloroformate (5.66 μl, 0.073 mmol) was added to a solution of 2-((2-chloro-5-cyano-3-(hexahydro-1H-pyrrolo[3,2-c]pyridin-5(6H)-yl)phenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (Example 443F, 29 mg, 0.049 mmol) and triethylamine (0.020 ml, 0.146 mmol) in dichloromethane (2 mL) and the reaction mixture was stirred at room temperature overnight. Solvent was evaporated in vacuo and the crude intermediate was purified by flash chromatography on silica gel using an automated ISCO system (24 g column, eluting with 1-4% 2 N ammonia in methanol/dichloromethane) to give 28 mg of methyl 5-(2-chloro-5-cyano-3-((7-cyano-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)octahydro-1H-pyrrolo[3,2-c]pyridine-1-carboxylate.
