実験手順

To a solution of 2-chloro-5-phenyl-N-(pyridin-2-ylmethyl)pyrrolo[2,1-f][1,2,4]triazin-4-amine (0.500 g, 1.49 mmol) and N-(tert-butyl)-2-(difluoromethyl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine-3-sulfonamide (0.697 g, 1.79 mmol) in 1,4-dioxane (5 mL) and water (1 mL) was added K2CO3 (0.412 g, 2.98 mmol). The reaction mixture was purged with nitrogen gas for 10 min. Then PdCl2(dppf)-CH2Cl2 (0.122 g, 0.149 mmol) was added and heated at 100° C. for 1 h in micro wave. The reaction mixture was allowed to cool to ambient temperature. The reaction mixture was filtered through CELITE® bed and the bed was washed with EtOAc (2×50 mL). The filtrate was diluted with water (50 mL) and extracted with EtOAc (100 mL). The combined organic extracts were dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. The resulting residue was purified by CombiFlash (REDISEP®, silica gel, 40 g, 40% EtOAc/hexanes) to obtain N-(tert-butyl)-2-(difluoromethyl)-5-(5-phenyl-4-((pyridin-2-ylmethyl)amino)pyrrolo[2,1-f][1,2,4]triazin-2-yl)pyridine-3-sulfonamide (0.600 g, 71.5% yield) as a pale yellow solid. LCMS Condition B-83: retention time 1.84 min, [M+1]=564.0. 1H NMR (400 MHz, CD3OD) δ ppm 1.26 (s, 9H), 4.94 (s, 2H), 6.81 (d, J=2.8 Hz, 1H), 7.27-7.31 (m, 1H), 7.44-7.55 (m, 3H), 7.59-7.63 (m, 4H), 7.77-7.82 (m, 2H), 8.43 (d, J=4.4 Hz, 1H), 9.19 (dd, J=2.0 Hz, J=1.2 Hz, 1H), 9.64 (d, J=2.0 Hz, 1H).
