反応手順
3-fluorophenylboronic acid (0.092 g, 0.66 mmol) was added to a suspension of 4-((6-chloro-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)methoxy)-7-methoxyquinoline (0.150 g, 0.44 mmol) in 2.5 mL dimethylformamide, followed by the addition of potassium carbonate (0.18 g, 1.3 mmol) in 0.6 mL water. PdCl2(dppf)-CH2Cl2 adduct (0.018 g, 0.022 mmol) was added and the flask was purged with argon, sealed and heated at 80° C. for four hours. Purification by MPLC (eluted with 5 then 10% MeOH in CH2Cl2) afforded the product as an off-white solid (78 mg, 44%). (ESI, pos. ion) m/z: 402.1 (M+H).
