Versuchsvorschrift

TMS-OTf (0.281 ml, 1.553 mmol) was added to a solution of tert-butyl 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 (360 mg, 0.518 mmol) and 2,6-lutidine (0.181 ml, 1.553 mmol) in dichloromethane (3 ml) and the reaction mixture was stirred at room temperature for 2 hours. The reaction mixture was diluted with dichloromethane and washed with saturated sodium bicarbonate. The aqueous layer was extracted with dichloromethane two more times. The combined organic layers were 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 (40 g column, eluting with 5-40% ethyl acetate/hexanes). 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 (288 mg) was obtained as an off-white solid.
