実験手順

To a solution of 5-iodo-1-(tetrahydro-2H-pyran-2-yl)-1H-indazole (0.1 g, 0.305 mmol) in ACN (5 mL) were added N-(4-(difluoromethoxy)phenyl)-6-vinylpyridazin-3-amine (0.080 g, 0.305 mmol), tri-o-tolylphosphine (0.037 g, 0.122 mmol), and triethylamine (0.127 mL, 0.914 mmol). The reaction mixture was purged with nitrogen for 5 min. Tris(dibenzylideneacetone)dipalladium(0) chloroform adduct (0.032 g, 0.030 mmol) was added and the reaction mixture was heated at 90° C. for 18 h. The reaction mixture was filtered through a pad of celite and rinsed with ethyl acetate. The organic layer was concentrated and purified by flash chromatography on silica gel using ethyl acetate/hexane to give (E)-N-(4-(difluoromethoxy)phenyl)-6-(2-(1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-yl)vinyl)pyridazin-3-amine as apale yellow solid (0.13 g, 87%). LCMS (ES-API), m/z 464.6 (M+H).
