Reaction Steps
A mixture of pyridine-3-boronic acid 1,3-propanediol cyclic ester, 4-bromoiodobenzene (1.1 eq), [1,1′-bis (diphenylphosphino)ferrocene]dichloropalladium(II) (0.05 eq) and 2M aqueous sodium carbonate (5 eq) in N,N-dimethylformamide (2 ml/mmol) was stirred at 85° C. for 4 hours. After quenching with saturated aqueous ammonium chloride solution, the mixture was partitioned between ethyl acetate and water, and the crude product from the organic phase was chromatographed on silica gel eluting with a 1:9 mixture of ethyl acetate and hexane to afford the 3-(4-Bromophenyl)pyridine compound as a solid.
