7-(2-chloro-5-methoxy-phenyl)-5-methyl-benzo[1,2,4]triazin-3-ylamine (0.333 mmol, 1.0 equiv), 3-bromo-N-(2-dimethylamino-ethyl)-benzenesulfonamide (0.499 mmol, 1.5 equiv), Cs2CO3 (0.999 mmol, 3.0 equiv), Pd2(dba)3 (0.0333 mmol, 0.1 equiv), and Xantphos (0.0666 mmol, 0.2 equiv) were dissolved in 7 mL dioxane. The reaction was placed under an argon atmosphere and refluxed at 100° C. for 18 h. The organics were filtered to remove excess inorganics, dissolved in EtOAc, washed with saturated NaHCO3 and brine, dried over Na2SO4 and concentrated under reduced pressure to give 3-[7-(2-chloro-5-methoxy-phenyl)-5-methyl-benzo[1,2,4]triazin-3-ylamino]-N-(2-dimethylamino-ethyl)-benzenesulfonamide, which was precipitated using EtOAc/hexanes (1:5 v/v) to give a dark orange solid (168.4 mg, 96% yield). Rf=0.50 MS (ES+) m/z=527.
