Reaction Steps

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 (58 mg, 0.097 mmol), anisole (0.043 ml, 0.390 mmol) and 25% TFA in dichloroethane (2 ml, 6.49 mmol) was heated at 35° C. overnight. Solvent was evaporated in vacuo and the crude was dissolved in acetonitrile (1 ml) and neutralized with 2N ammonia in methanol (1 ml). The crude product was purified by flash chromatography on silica gel using an automated ISCO system (24 g gold column, eluting with 1-12% 2 N ammonia in methanol/dichloromethane). 2-((2-chloro-5-cyano-3-(hexahydro-1H-pyrrolo[3,2-c]pyridin-5(6H)-yl)phenyl)amino)-4-(cyclopropylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (41 mg) was obtained as a white solid.
