Participants

Reaction Steps

2-Bromo-4-methylpyridine (0.195 mL, 1.74 mmol), 2-aminopyridine (180 mg, 1.91 mmol), potassium tert-butoxide (293 mg, 2.61 mmol), (±)-BINAP (4.3 mg, 6.96 mmol) and Pd2(dba)3 (4 mg, 4.35 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 (100:1 to 100:2) to furnish I as a yellow solid (249 mg, 77%).
