실험 절차
A mixture of tert-butyl 4-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-yl]piperazine-1-carboxylate (46.3 mg, 0.119 mmol, Aldrich, Cat. No. 654337), N-[3-(7-chloroimidazo[1,2-b]pyridazin-3-yl)phenyl]-N′-(2,2,2-trifluoroethyl)urea (40.0 mg, 0.108 mmol, Example 30, Step 3), tetrakis(triphenylphosphine)palladium(0) (6.25 mg, 0.00541 mmol) and sodium carbonate (34.4 mg, 0.324 mmol) in dioxane (1 mL) and water (0.3 mL) was degassed and recharged with nitrogen three times, and heated and stirred at 110° C. for 3 h. After cooling, the mixture was diluted with ethyl acetate, washed with water and brine. The organic layer was dried over MgSO4, filtered and concentrated under reduced pressure. The residue was the desired product which was directly used in next step without further purification. LCMS (M+H)+: m/z=597.2.
