4-Alkyl- and 4-benzyl-substituted 3,3'-oxybispyridines: An efficient synthesis at room temperature

Article abstract of DOI:10.1055/s-1996-4287

Several new 4-alkyl- and 4-benzyl-substituted 3,3'-oxybispyridines 1 are accessible at room temperature in high yields from 3-hydroxypyridine, potassium salt derivatives 7 and 3-bromo-4-nitropyridine 1-oxide (5d), which are readily available starting materials. The reactivity of 5d depends on the solvent.
