The flask was evacuated and backfilled with N2 3×, then heated at 100° C. for 1 h. The reaction was cooled to room temperature and filtered through celite, rinsing with EtOAc. The solvent was removed in vacuo. The material was purified by flash column chromatography (0%-50% EtOAc/DCM; 80 g column). 2-((2-chloro-5-cyano-3-(4-hydroxybutan-2-yl)phenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (179 mg) was obtained as an orange glass.
