실험 절차

1 g (2.9 mmol) 9-Bromo-2-chloro-3-phenylpyrimido[1,2-b]indazole (intermediate example Int-1-2), 1.09 g (2.9 mmol) {1-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]cyclobutyl}carbamic acid tert-butyl ester, 322 mg (0.28 mmol) tetrakis(triphenylphosphine)palladium and 886 mg (8.4 mmol) sodium carbonate in 30 mL dioxane and 4.2 mL water were heated over night at 105° C. The reaction mixture was poured on water/dichloromethane and vigorously stirred for 30′. The organic phase was separated, washed with brine, dried, filtered, and the solvent was evaporated. The residue was purified by HPLC yielding 346.4 mg (20.6%) of the title compound.
