Versuchsvorschrift

To the stirred solution of 2-((2-chloro-5-cyano-3-(4-(2,2-difluoroethyl)-piperazin-1-yl)phenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (120 mg, 0.194 mmol) in dry dichloromethane (2.0 mL) was added anisole (0.1 mL, 0.915 mmol) and trifluoroacetic acid (0.3 mL, 3.87 mmol) at room temperature. The reaction mixture stirred at room temperature for overnight. On completion of the reaction, the reaction mixture was diluted with dichloromethane and washed with saturated sodium bicarbonate. The organic layer was separated and aqueous layer was extracted with dichloromethane twice. The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo to give off-white solid. This was purified by preparative HPLC to afford 2-((2-chloro-5-cyano-3-(4-(2,2-difluoroethyl)piperazin-1-yl)phenyl)amino)-4-(cyclopropylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (50 mg, 0.098 mmol, 50.5% yield) as an off-white solid
