2-Methoxypyridine-5-boronic acid (116 mg, 0.758 mmol), Tetrakis(triphenylphosphine)palladium(0) (46 mg, 0.040 mmol) and 5-Chloro-7-iodo-2-methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazine (0.152 g, 0.467 mmol) were placed in a vial, followed by 1,4-Dioxane (3.00 mL) and 2.00 M of Sodium carbonate in Water (1.00 mL, 2.00 mmol). The sample was frozen, placed under vacuum, sealed, warmed, refrozen, evacuated, then placed under nitrogen and heated in a 60° C. block. When complete, the sample was partitioned between EtOAc and water (30 mL each), the aq. extracted (EtOAc 3×20 mL) and the comb. organics washed with brine. Purification (ISCO, 12 g, 0-30% EtOAc:Hex) afforded 5-Chloro-7-(6-methoxy-pyridin-3-yl)-2-methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazine (0.116 g, 81%).
