Several new 4-alkyl- and 4-benzyl-substituted 3,3’-oxybispyridines 1 are accessible at room temperature in high yields from 3-hydrosypyridine, 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.
