実験手順

2-Bromoquinoline, I (500 mg, 2.40 mmol), 2-aminopyridine (249 mg, 2.64 mmol), tBuOK (404 mg, 3.60 mmol), (±)-BINAP (6 mg, 0.01 mmol) and Pd2(dba)3 (5.5 mg, 0.006 mmol) were stirred in toluene (10 mL) at 90° C. under Ar(g) for 21 h. The reaction mixture was then diluted with CH2Cl2 (10 mL) and silica was added, followed by the removal of the solvent under reduced pressure. The resulting dry load material was purified by silica gel column chromatography eluting with CH2Cl2/MeOH (100:1 then 100:2) to furnish II as a colourless oil (344 mg, 45%).
