Participants

Reaction Steps

According to the procedure described in Example 1(a) for the preparation of 3-biphenyl-4-yl-furan, 4-bromopyridine hydrochloride (500 mg, 2.57 mmol) was coupled to fresh 3-furanboronic acid (see Thompson, W. J.; Gaudino, G. J. Org. Chem. 1984, 49, 5237-5243) to furnish 373 mg(100%) of crude 4-furan-3-yl-pyridine as an unstable solid that was used immediately. NMR and IR matched that of literature (see Ribereau, P.; Queguiner, G. Can. J. Chem. 1983, 61, 334-342 and Ishikura, M.; Ohta, T.; Terashima, M. Chem. Pharm. Bull. 1985, 33, 4755-4763).
