Reaction Steps

Na2CO3 (1.117 mL, 2.234 mmol) followed by Pd(PPh3)4 (51.6 mg, 0.045 mmol) were added to a solution of iodobenzene (0.1 mL, 0.894 mmol) and 2-bromopyridine-5-boronic acid (271 mg, 1.340 mmol) in DMF (4 mL). The reaction was heated at 60° C. for 4 h, cooled and concentrated. The residue was partitioned between EtOAc and water. The organic phase was washed with brine, dried (MgSO4), and concentrated. Chromatography over silica eluting with 4:1 hexanes:EtOAc afforded the title compound as an off-white solid. LC-MS: calculated for C11H8BrN 234.09, observed m/e 236.5 (M+H)+ (Rt 1.72 min).
