Procedure

4-(2-chloro-5-cyano-3-((7-cyano-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)-N,N-dimethylpiperazine-2-carboxamide (38 mg, 0.061 mmol, Example 563D) was taken up in DMF (0.5 mL) and Cs2CO3 (39.5 mg, 0.121 mmol) and 2-bromo-1,1-difluoroethane (5.79 μl, 0.073 mmol) were added. The reaction was heated at 80° C. for 2 h. The reaction mixture was cooled to room temperature and diluted with EtOAc. The organic layer was extracted 2× with water and once with brine, then dried over Na2SO4, filtered, and concentrated. 4-(2-chloro-5-cyano-3-((7-cyano-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)-1-(2,2-difluoroethyl)-N,N-dimethylpiperazine-2-carboxamide (37 mg) was obtained as an orange glass. The crude material was taken onto the next step.
