Palladium acetate (25.5 mg, 0.114 mmol) and triphenylphosphine (65.6 mg, 0.250 mmol) were dissolved in 1,4-dioxane (2.00 mL) and the mixture was purged with nitrogen for 10 minutes. (7-Bromo-pyrrolo[2,1-f][1,2,4]triazin-2-yl)-[4-(4-methyl-piperazin-1-yl)-phenyl]-amine (110 mg, 0.284 mmol), 4-[(4-boronophenyl)methyl]-thiomorpholine 1,1-dioxide (306 mg, 1.14 mmol), N,N-dimethylformamide (2.00 mL) and 1.50 M sodium carbonate in water (0.379 mL, 0.568 mmol) were added. The reaction mixture was heated at 90° C. overnight and then partitioned between water (50 mL) and dichloromethane (50 mL). The organic layer was washed with water (50 mL) and brine (25 mL) and then dried over Na2SO4. Purification by silica gel chromatography using a gradient of 0-10% MeOH/DCM as the eluting solvent to obtain the title compound as a yellow-brown foam (151 mg, 100%).
