反応手順
2-Bromo-4-phenylpyridine (280 mg, 1.19 mmol), 2-aminopyridine (124 mg, 1.31 mmol), potassium tert-butoxide (201 mg, 1.79 mmol), (±)-BINAP (3 mg, 0.05 mmol) and Pd2(dba)3 (2.7 mg, 0.03 mmol) were stirred in toluene (2.5 mL) at 90° C. under Ar(g). After 17 h stirring, the reaction mixture was diluted with CH2Cl2 (2.5 mL) and silica was added. The solvent was removed under reduced pressure and the resulting dry loaded material purified by silica gel column chromatography, eluting with CH2Cl2/MeOH (100:2), to furnish I as a yellow solid (183 mg, 62%).
