実験手順

tert-butyl 4-(3-cyano-5-((7-cyano-4-(ethyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)-1H-indol-1-yl)piperidine-1-carboxylate (500 mg, 0.503 mmol) was mixed with anisole (0.5 mL, 4.58 mmol) and DCE (5 mL). TFA (1 mL, 12.98 mmol) was added. The mixture was stirred at 25° C. for 24 hrs. LC/MS showed product formation. The mixture was concentrated to dryness, diluted with MeOH and applied onto a cartridge of Phenomenex Strata-X-C 33 um cation mixed-mode polymer. This was washed with methanol and product was eluted with 2 N solution of ammonia in methanol. Removal of the solvents left 2-((3-cyano-1-(piperidin-4-yl)-1H-indol-5-yl)amino)-4-(ethylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (80 mg) as solid.
