To a stirred solution of 5-iodo-1-(tetrahydro-2H-pyran-2-yl)-1H-indazole (0.05 g, 0.152 mmol) in ACN (5 mL) were added N-(4-(trifluoromethyl)phenyl)-4-vinyl-1,3,5-triazin-2-amine (0.041 g, 0.152 mmol), tri-o-tolylphosphine (0.019 g, 0.061 mmol) and triethylamine (0.064 mL, 0.457 mmol). Nitrogen was purged for 5 minutes. Tris(dibenzylideneacetone)dipalladium(0) (0.014 g, 0.015 mmol) was added and the reaction mixture was heated at 90° C. overnight. The reaction mixture was filtered through a pad of celite, washed with ethyl acetate, and the organic layer was concentrated. The crude product was purified by flash chromatography on silica gel using 25% ethyl acetate in hexane to give (E)-4-(2-(1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-yl)vinyl)-N-(4-(trifluoromethyl)phenyl)-1,3,5-triazin-2-amine as a pale yellow solid (0.04 g, 42% yield). LCMS: R.T.=1.21 min; [M+H]+=467.33.
