Reaction Steps

400 mg (1.12 mmol) 10-Bromo-2-chloro-3-phenylpyrimido[1,2-b]indazole, intermediate example Int-1-3, 172.1 mg (1.17 mmol) 4-cyanophenylboronic acid, 91 mg (0.112 mmol) bis(diphenylphosphino)ferrocenedichloropalladium(II) and 354.6 mg (3.35 mmol) sodium carbonate in 12 mL degassed dioxane and 1.68 mL water were heated in the microwave for 45 min. at 105° C. The reaction mixture was poured on a mixture of water/saturated ammonium chloride/dichloromethane and stirred vigorously for 30′. The organic phase was separated, washed twice with brine and dried (sodium sulfate). After filtration and evaporation of the solvent the residue was purified by HPLC yielding 114 mg of the title compound.
