실험 절차

In a dry 25 mL round bottom flask, 5-methyl-7-(3-nitro-phenyl)-benzo[1,2,4]triazin-3-ylamine (0.223 g, 0.7935 mmol, 1 equiv), 4-bromo-N-(2-pyrrolidin-1-yl-ethyl)-benzenesulfonamide (0.396 g, 1.19 mmol, 1.5 equiv), cesium carbonate (0.776 g, 2.38 mmol, 3 equiv), 4,5-bis(diphenylphosphino)-9,9-dimethyl xanthene (0.092 g, 0.159 mmol, 0.2 equiv) and tris(dibenzylideneacetone) dipalladium (0.073 g, 0.079 mmol, 0.1 equiv) were combined. The reactants were flushed with argon, diluted with dioxane (10 mL) and outfitted with a reflux condenser. The reaction was heated to reflux for 5 hours, then filtered hot and the solvents were evaporated. Silica gel column purification provided desired product as a yellow powder (0.16 g, 39% yield). MS (ESI+): m/z=582.1
