Versuchsvorschrift

7-(2-chloro-5-nitro-phenyl)-5-methyl-benzo[1,2,4]triazin-3-ylamine (0.65 mmol, 1.0 equiv), 4-bromo-N-(2-pyrrolidin-1-yl-ethyl)-benzenesulfonamide (0.95 mmol, 1.5 equiv), Xantphos (0.065 mmol, 0.10 equiv), Pd(OAc)2 (0.033 mmol, 0.05 equiv), and potassium-t-butoxide (1.3 mmol, 2.0 equiv) were dissolved in 45 mL of dioxane and placed under an argon atmosphere. The reaction mixture was refluxed at 100° C. for 18 h and then cooled to room temperature. Inorganic salts were filtered out of solution and the organics were concentrated under reduced pressure. The residue was precipitated using EtOAC/hexanes (1:5 v/v) to afford 4-[7-(2-chloro-5-nitro-phenyl)-5-methyl-benzo[1,2,4]triazin-3-ylamino]-N-(2-pyrrolidin-1-yl-ethyl)-benzenesulfonamide, as a red solid (232 mg, 63% yield). Rf=0.42 MS (ES+) m/z=570. LC retention time 2.56 min.
