実験手順

Palladium(II)acetate (0.002 g, 0.009 mmol) was dissolved in dioxane (0.5 mL), and treated with triphenylphosphine (0.009 g, 0.035 mmol). The mixture was degassed twice before adding ethyl Intermediate AY (4-amino-7-bromo-5-{4-[({[4-(trifluoromethyl)pyridin-2-yl]amino}carbonyl)amino]phenyl}pyrrolo[2,1-f][1,2,4-]triazine-6-carboxylate (0.05 g, 0.009 mmol)), 3-fluorophenylboronic acid (0.014 g, 0.097 mmol) and aq. Na2CO3 solution (0.11 mL, 0.22 mmol, 2M). The mixture was heated to 80° C. overnight. The reaction was then cooled and filtered through silica. The filtrate was concentrated then triturated with EtOAc. The product was collected by filtration to give 20 mg of a tan solid (39%). 1H-NMR (THF-d8) δ 10.59 (bs, 1H) 9.08 (s, 1H), 8.47 (d, J=5.1, 1H), 7.79 (s, 1H), 7.73-7.68 (m, 3H), 7.41-7.37 (m, 5H), 7.23 (d, J=5.2, 1H), 7.13-7.08 (m, 1H), 3.94 (q, J=7.1, 2H), 0.90 (t, J=7.1, 3H); MS [M+H]+=580.0; LCMS RT=3.41.
