Procedure

4-(cyclopropyl(4-methoxybenzyl)amino)-2-(methylsulfonyl)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (Intermediate 3) (58.4 mg, 0.146 mmol), methyl (3-amino-4-fluoro-5-(4-(oxetan-3-yl)piperazin-1-yl)phenyl)(4-methoxybenzyl)carbamate (62 mg, 0.098 mmol) and Cs2CO3 (95 mg, 0.293 mmol) in DMF (1 ml) were heated at 70° C. for 80 minutes. Additional 4-(cyclopropyl(4-methoxybenzyl)amino)-2-(methylsulfonyl)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (58.4 mg, 0.146 mmol) and Cs2CO3 (95 mg, 0.293 mmol) were added and the mixture stirred at 45° C. for 16 hours. The mixture was partitioned between EtOAc and dilute aq. NH4Cl solution. The organic layer was washed twice with dilute NaHCO3 solution, once with brine, then dried over MgSO4, filtered and evaporated to dryness to give methyl (3-((7-cyano-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)-4-fluoro-5-(4-(oxetan-3-yl)piperazin-1-yl)phenyl)(4 methoxybenzyl)carbamate (134.4 mg). The material was used in the following reaction without further purification.
